mysqld shows high cpu usage over extended time, restart = normal

Occasionally in checking one of the servers, I noticed that mysql shows 85% + of
cpu usage essentially leaving the server at 0% idle. After monitoring it for a
few hours, the status did not change. After a stop and start of mysql, things
progessed normally. Checking back a few days later I noticed it was once again
sitting up there at 95% (or thereabouts) and doing nothing of value from what i
could tell.

Have restarted MySQL during peak usage times for that server and its database,
and it has showed normal loads and CPU usage (approx 20% CPU with .1 to .3
load). Is there a known issue (running on FreeBSD 4.8, MySQL 3.23.55 MyISAM)?
Is there something I should check when next I notice the high CPU usage?

Thanks

Dave

I've been searching the mailing list for a solution to my problem with "mysqld got signal 11;" and I haven't seen any answers that might help me. This is the situation. I have a db that is being accessed intensively about 400 connections during the wee at a time. I noticed the problem at first with 4.0.13 and tried 3.23.57 and now 4.0.14 with the same problem. I've run the db on FreeBSD 5.1 and 4.8, again same problem. This is what...

This is my 5th or 6th server (both Unix and Windows varieties). In the past I've gotten the message "ERROR 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (222)". In the past, I've either asked someone else to start the server or just tried everything I could until the server started. This time, I took a systematic approach, and noted every step. What finally worked was typing the command "service...

Hi ! I installed mysql on windows xp. The first time I started mysld, there is no problem. But, now, each time I start mysqld, I must change the port in my.xxx else I got the following error : "Do you already have another mysqld server running on port : 3306 ?" etc... I stop mysqld with : "mysqladmin -u root shutdown". So, why I can't use the same port each time ?

Hello, I'm exploring why one of my C# .NET apps has "high" memory usage, and whether I can reduce the memory usage. I have an app that wakes up and processes text files into a database periodically. What happens, is that the app reads the contents of a text file line by line into an ArrayList. Each element of the ArrayList is a string representing a record from the file. The ArrayList is then processed, and the arraylist goes out of...

Ok, I restart the aspnet_wp.exe, memory usage is at about 3 mb, the first time I run one of my asp.net apps, the memory usage shoots to 30 mb usage and remains there. Even if I close the IE window that I am running my app in, the memory is not freed up. Is this normal? I am imagining that the GC never cleans out the memory that aspnet_wp is using. Thank you

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
