MySQL不能创建新线程(errno 12)

I'm runnning MySQL 5.0.45/ PHP Version 5.2.6 / CentOS with Plesk.

我使用Plesk运行MySQL 5.0.45/ PHP版本5.2.6 / CentOS。

I get occasionaly a burst of "Can't create a new thread (errno 12); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug"

我偶尔会出现“无法创建新线程(errno 12)”;如果您没有超出可用内存，您可以参考手册，寻找可能依赖于os的错误。

Global memory is not the issue since I have about 620M free.

全球内存不是问题，因为我有大约6.2亿的空闲时间。

Anyone know what could be the cause for this?

有人知道这是什么原因吗?

Thanks

This is bug 20815, mysql is using too much stack space for threads. Try upgrading to at least 5.0.48 or 5.1.21.

Any ulimit style restrictions?

ulimit风格限制吗?

Otherwise AppArmor or things like that come to mind.
