since a few hours our server hangs every time you do a session_start.
For testing purposes i created a script which looks like this:
There are many reasons for that, here are a few of them:
A. The session file could be opened exclusively.
When the file lock is not released properly for whatever reason, it is causing
session_start() to hang infinitely on any future script executions.
session_set_save_handler() and make sure the write function uses
fopen($file, 'w') instead of fopen($file, 'x')
B. Never use the following in your php.ini file (entropie file to "
/dev/random"), this will cause your
session_start() to hang:
<?php ini_set("session.entropy_file", "/dev/random"); ini_set("session.entropy_length", "512"); ?>
session_start() needs a directory to write to.
You can get Apache plus PHP running in a normal user account. Apache will then of course have to listen to an other port than 80 (for instance, 8080).
Be sure to do the following things:
- create a temporary directory
php.ini and set session.save_path to the directory you just created
Otherwise, your scripts will seem to 'hang' on
