There were a lot of warnings in apache's error_log *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b11590 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b12a78 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b1aa30 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x0a399120 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (!prev): 0x0a3eab68 *** etc.. Mainly while using DokuWiki or phpMyAdmin After I changed session handler from sqlite to files, problem dissapeared. Now it's a week with files session handler and no new entry in log saying something about glibc error. So I am sure, it's caused by sqlite session handler.

I have checked configuration of PHP. Default php.ini-dist worked, so I make diff between mine and default. Main difference was in method of saving sessions. We were using sqlite. When I changed it to default, files type, everything is now OK. I leave this, files session configuration run for a longer period, but I think, problem was i sqlite.

I've sucessfully downgraded to same glibc version as on other server is. Than recompiled apache and php again with this older libc, but this errors appears in log again. Sometimes it causes exit signal Segmentation fault(11) and sometimes "only" exit signal Aborted (6). *** glibc detected *** double free or corruption (out): 0x08408b78 *** *** glibc detected *** double free or corruption (!prev): 0x0840d220 *** I am sorry for bothering but I going to be quite desperate about this problem, because I still don't know why it happens.
