I wondered if anyone has come across this before or can think of ways to help me debug this further.
I have thousands of users all login and gain sessions perfectly fine, but every so often (maybe once a day) I get the following error:
PHP Warning: session_start(): open(C:\Windows\Temp\sess_n6cbb6rtg8p9p11fohjdt6btd6, O_RDWR) failed: Permission denied (13) in C:\inetpub\wwwroot\login.php on line 31
The folder has full write permissions as otherwise I would have thousands of these errors.
The only thing I can possibly think of is some sort of file-lock for that session that has gone wrong, but I cant think how.
Any suggestions welcome.
