ID: 19022 Comment by: phpbugs@mx4k.com Reported By: phpbugs@mx4k.com Status: Bogus Bug Type: Session related Operating System: linux (rh7.3), apache 1.3.26 PHP Version: 4.2.1 New Comment: sorry, no. (believe me i wouldnt post here if i could find any reasons why my OS/Fs should screw up the files) FYI I have tried LOTS of stuff but this problem persists.

Previous Comments: ------------------------------------------------------------------------ [2002-08-21 13:33:19] sander@php.net Maybe there's not enough space at /tmp. Probably not a bug in PHP. ------------------------------------------------------------------------ [2002-08-21 11:14:17] phpbugs@mx4k.com hi there, i have a webserver running rh7.3 with apache 1.3.26 and php4.2.1 as module. At random (not reproduceable reasons) all my session data gets lost. the session file exists but all data written there in previous scripts is gone. All i get a hundreds of errors in my logfiles (like these): [21-Aug-2002 16:47:07] PHP Warning: Failed to write session data (files).
