Hi,

I've been trying to track down more information on this Apache error:

[Wed Apr 07 12:25:49 2010] [warn] (12)Not enough space: mpm_get_completion_context: Failed to create the transaction pool.

which causes Apache to crash and requires restarting the server. Can someone provide an explanation as to the cause of this error? Also, if there are any suggested resolutions? I've seen one posting suggesting that upgrading to a new version (we're on 2.0.54) "may" resolve the problem but we've got hundreds of servers running with that version having no problems, just the one that's failing.

Thanks

I've seen this error only once. If your server or the vps memory surpasses 2G that error can appear. How is the memory usage on the server? Heavyload?

Maybe a solution can be that apache restarts itself after many requests to free the memory.
e.g.
Code:

MaxRequestsPerChild 1000

The default value for windows is 0 so it runs endless.

Even if you run many servers you should upgrade all servers to 2.2 or at least upgrade to the last 2.0 version.

James,

Thanks for the response. We'll look into the MaxRequestsPerChild Apache param.
