Replication Master Crashed After 6 Hours

CK
Hello everyone,

I recently setup replication, the master and slaves appears to work
fine initially. After about 6 hours, the master mysqld process will
start to consume 99% CPU and the load (avg. load per minute) will go
to 3, 4, 6, 15, 24, 56, 312... in a matter of seconds! The master then
stops responding and needs a reboot. This problem is reproducible, I
have tested a few times.

This is a screenshot of "top" command just before the master died:

There are plenty of memory and no disk swapping when the master goes
99%. Error and slow logs don't show any useful information.

Can anyone shed some light?

Thanks in advanced.

Regards,
CK

Hi all, I am looking at a problem we encountered with replication. Our front-end and back-end are Microsoft Access 2000. We have a design master at the server and replicas at five notebooks. The notebooks are synchronized daily by the users via a form that uses Microsoft Jet and Replication Objects (JRO) and this works well. I have a few questions about this: 1. A problem occurs when two users change the same field in the same record

I came up with a replication configuration that is basically the result of all the restrictions of replication as well as the restrictions of allowable software on work PC's and I was curious if anyone would point out any flaws or possible problems with the design. I'm limited to Access 2000 professional edition (Thus I cannot use indirect sync or internet sync) and cannot install anythird party controls (i.e.

all, I've just tried to re-start a replication process and the slave's tables came up marked as crashed. I'm doing a repair on one of them but there are a lot of databases/tables so I can't check them all (or is there a table entry somewhere that flags crashed tables?) Here is the sequence I used: On Slave (FreeBSD-6.0): Stop slave using stop slave

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.

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,...
