I have a handful of sites on this VPS using WordPress on them and not all the same theme or plugins.
reviewed htaccess turned off and on plugins.
Disabled ClamAV (was eating memory) tried changing the php.ini all to no avail.
This just started happening a 1.5weeks ago and I am totally at a loss.
Do we have any burst/swap on VPS - with less than 10 sites with little traffic this shouldn't be a problem?
What is your memory limit set to in the php.ini editor in WHM? You don't want a single script to use all your memory, but you can try upping to 128mb or 256mb.
I've kept bumping it up and now its 512M - hoping that it would work to no avail.
