i'm running my site on a VPS with apache/php/fastcgi/mysql - occasionally (1 in every 30 requests or so), when i open a page it seems to hang until it times out and returns a 500 error.

  • I do not have a reproducible pattern but it seems to occur more when posting a form, but also happens sometimes when just clicking on a page.
  • This happens even at times when there is close to no load on the VPS.
  • I have eliminated both php and mysql as a possible cause of the problem (the request does not even reach the php script when this happens).
  • If i close the browser window (while it's not responsive) and open the same url again, it doesn't open, it still does not respond till it timeouts.

I know this is a bit of a general question but any pointers are much appreciated.
