MySql Error Can't create a new thread (errno 11).?

I am getting this error at times when I have light traffic, and the server is not overloaded, and memory is available.

mysql_select_db(): Can't create a new thread (errno 11). If you are not out of available memory, you can consult the manual for a possible OS-dependent bug in

I am on a a VPS with Virtuozzo, it runs on Redhat 7.3,

mysql (4.0.15-standard), php 4.3.3.

I am running PHP Nuke and have not had this error and have run for months. I have not tweaked or changed mysql or php.

Any help would be appreciated.

Perhaps you should upgrade your Redhad distro to the latest version. This might be a known bug in the OS which has been fixed in new versions

I have no evidence of this, but I do know they're up to at least 9.0 now

I can not go up to 9.0 the Virtual Private Server runs on 7.3. So I might be screwed.

It may not even fix the problem... only a suggestion...
How about upgrading your mysql version?

Have you tried restarting the webserver and/or mysql server?

I just searched google and found lots of different answers in other forums... some suggestions were restart the server... don't use mysql_pconnect() (in PHP)... change max_used_connections (in my.cnf) to 10 (That'll get the connections to die off after 10 seconds)

Hopefully something here will help ya? =)

Here's my google search

I have restarted and things are better for the last 14 hours, I do not use the pcconnect so I will look into the max_used_connections (in my.cnf) to 10 (That'll get the connections to die off after 10 seconds)

Thanks I will try it out.
