Yesterday I faced with really weird issue with PHP’s session handling. At work we are hosting dozens of sites on our servers and suddenly on one server we were getting lot of weird out of space errors when PHP tried to open session files. Error message was “Warning Unknown: open(/path/to/sessions/sess_somehash, O_RDWR) failed: No space left on device (28)” . Because of those errors I was believing we were somehow running out of space on apache’s temp file partition. Truth was there was only few megabytes data, but the problem was that we had over 200 000 files on one folder and PHP got crazy of that.
