Has anyone experienced Apache hitting the MaxClients limit and hanging?   We've had this happen on several boxes
since upgrading to 4.01.   We've had to restart Apache to get them functioning again.  We've upped the
MaxClients limit on them, but it still occurs even after doubling the setting to 512.   These are high perfomance
boxes, so it doesn't seem like it should be a CPU issue.

 

There shouldn’t be a lot of connections to the HTTP server during normal operations; MeshConfig and task setup from remote nodes are the only things that should be connecting.  The internal parts of pScheduler poke the database directly.

 

If you encounter that again, I’d be interested to see what the process table and netstat say about what’s connected and from where and if there are old processes that connect and aren’t dying.
