Trouble with huge amount of State Server Sessions Timed out

P: n/a
Hi,

I have a web application which sometimes throws an “out of memory”
exception. To get an idea what happens I traced some values using performance
monitor and got the following values (for one day):

\\FFDS24\ASP.NET Applications(_LM_W3SVC_1_Root_ATV2004)\Errors During
Execution: 7

\\FFDS24\ASP.NET Apps v1.1.4322(_LM_W3SVC_1_Root_ATV2004)\Compilations
Total: 10

\\FFDS24\ASP.NET Apps v1.1.4322(_LM_W3SVC_1_Root_ATV2004)\Errors Total: 7

\\FFDS24\ASP.NET v1.1.4322\State Server Sessions Timed Out: 2999

\\FFDS24\ASP.NET v1.1.4322\State Server Sessions Total: 3008
Could somebody please provide me with some background information on those
values? What exactly would be an Errors During Execution? And what could be
the reason for this huge amount of State Server Sessions Timed out?

Processor time was < 2% for the whole day and the server almost always had
1GB of free RAM.
Thank you a lot in advance!

Hi Daniel,

Welcome to ASPNET newsgroup.
From your description, you're currently suffering a out-of-memory excpetion
on your webserver that host the ASP.NET application. Also from the perfmon
log, you found that there're huge numbers of StateServer Session time out
entries.

Well, for the

\\FFDS24\ASP.NET v1.1.4322\State Server Sessions Timed Out: 2999

\\FFDS24\ASP.NET v1.1.4322\State Server Sessions Total: 3008

entries they're only meaningful to server which is configured to running
asp.net state service , providing session state server for other remote
machines(also local). So is your problem server confgured as state server?

Also, how many asp.net apps are there running on your problem server and
can you try isolate the problem to only a particular web app among them?
If we can isolate the problem to a certain web app , it'll be much helpful
for us to look into it futher.

Thanks,

Hello Steven,

thank you for your reply! As I missed to mention and you most probably
already guessed the application having the problem is configured using a
state server running on exactly the same machine as the application is
running on. This server also hosts another couple of (tiny) applications
which all are configured to manage their session state inProc. Therefore the
problem I am facing is only specific to this certain application.

What information do you need to track down the problem?

Would you happen to have a documentation of the entries of the Performance
monitor? The explanations which come with performance monitor are not exactly
ausführlich. I still don’t know for example what Errors During Execution are
and when the application would be compiled. Where would I get details about
this performance counters?

Thank you Steven! Your help is greatly appreciated!

Hi Daniel,

Thanks for your followup.
Based on my experience, inspite of some code related problems such as
memory leak , we can first try checking some common things which may cause
the problem. One most common issue is that when we deploy our release
version app the the server, we haven't changed the "compilation" element's
"debug" attrribute to false. Like:

<compilation debug="false"/>

So is the certain asp.net webapp's web.config debug mode turned off? If
not, since the ASP.NET runtime won't use batch compilation for the pages or
other dynamnic compiled resources, it'll make those compiled pages or
components in separate assemblies and make the memory divdided into
individual sections. Thus, it's possible to cause memory fragment that'll
cause allocate large block of memory failed.

In addition, since the ASP.NET has workprocess recycle setting on memory
limitation, that means the runtime will recycle the worker process when its
used memory size has exceed a certain configured value. Is your server 2k
server or 2003 server and how much is the total physical memory on the
server? For 2k server, the setting is in the <processModel> element in
machine.config, For 2003 server(iis6), we can configure it in the IIS's
application pool setting. So you can check whether you've set it memory
limit to a very high value so that the process won't recycle before the
used memory exceed that value.

Thanks,

Steven,

thank you for your answer. In fact, to my horror, I had to realize that
<compilation debug/> was set to true which I now changed to false.
As for your question regarding the server the application is hosted of a 2
processor xeon with 2 GB RAM and Windows 2003 Server. I checked IIS
Application Pool Settings and the only thing which is configured is “Recycle
worker process (in minutes)”. There are no settings configured for “Memory
recycling”. As I already mentioned there is almost always 1GB RAM available,
only for a couple of times when only 800MB were available. Recycling of the
process due to lack of memory should definitely not be a problem, at least
this is what I would have expected…

Greetings

Daniel

Hi Daniel,

Thanks for the followup. If the compiliation/@debug has already been turned
off and still encountering out-of-memory exceptions , the problem maybe
somewhat hard to troubleshoot form the surface. And currently I'm thinking
the problem maybe something related to the STATEserver session. Something I
wanted to point out is that storing data in the ASP.NET Session in the
State Service or SQL Server can be memory intensive depending on the types
of data being stored. The w3wp.exe process has to serialize the data
before saving it into session. This can result in 2 - 3 objects being
created for the serialization process to occur. If this occurs for a
dataset that is 100 MB in size, it could
potentially create 200-300 MB of objects to store it in session before the
request is complete. The following link has some information from one of
our developers outlining the differences in session and recommendations:

Understanding session state modes + FAQ
http://www.asp.net/Forums/ShowPost.a...=1&PostID=7504

So is there any particular large objects or non-seriazable objects which
your application frequently trying to store into out of process session?

BTW, looking at the nature of this issue, it would require intensive
troubleshooting(memory dump and analysis) which would be done quickly and
effectively with direct assistance from a Microsoft Support Professional
through Microsoft Product Support Services. So I also recommend you
consider opening a regular case for this issue if you feel it urgent and
critical.

Thanks,

| Steven,
|
| thank you for your answer. In fact, to my horror, I had to realize that
| <compilation debug/> was set to true which I now changed to false.
| As for your question regarding the server the application is hosted of a
2
| processor xeon with 2 GB RAM and Windows 2003 Server. I checked IIS
| Application Pool Settings and the only thing which is configured is
“Recycle
| worker process (in minutes)? There are no settings configured for
“Memory
| recycling? As I already mentioned there is almost always 1GB RAM
available,
| only for a couple of times when only 800MB were available. Recycling of
the
| process due to lack of memory should definitely not be a problem, at
least
| this is what I would have expected?

P: n/a
Steven,

In regards to your post on 7/24 below. I think I'm having a problem related
to this. I have app running on a windows 2003 web farm and after a couple
hours I get the error below . Even though this app runs OK on my dev machine
and during testing, half way through the day, one of the production servers
eventually seems to raise this. I am storing datasets in sessions but I don't
know how I can determine if this is the problem. If datasets can be a
problem, I'm not sure what I can do as a workaround....

My error...

"Unable to serialize the session state. Please note that non-serializable
objects or MarshalByRef objects are not permitted when session state mode is
'StateServer' or 'SQLServer'.
