Did you disable any exec functionality from php using disable_functions?

No, only thing thats been disabled (AFAIK) is APC caching.

Try a repair on the table first, run it a couple times.

Post up the error logs for php, when this is happening as well.

What caching system are you using?

Im using filecache, i'll take a look at the logs.

Id use memcache or xcache, versus the filecache.

Disable the filecache for now as well in your testing.

the system steup im using doesn't support xcache, i'll take a look at memcache, unfortunately im at work so can't ssh, i cant check the logs or change caching!

Any system would support xcache, as long as you install it, i assume your not on a vps/dedi?

are you trying to make a new mod if so i can give you site for testing i am not using will install what version u need

Don't ever repair or optimize a database if you don't have to. Repairs should only be run if the table is actually crashed. Optimize if and only if you've removed large groups of data from an myisam table.

If you run that query yourself, do you get any errors?

Without an error message hard to tell. php might have timed out and killed the query/connection. or MySQL timed out and killed the query, which made php exit and give you an error. But its weird you're not getting an error message.
