Quite curiously I had this same problem just yesterday and spent quite a bit of time scratching around trying to get it to work again. I upgraded all of apache, glibc and php to know avail. Though this error had been seen many times before by others i found nothing relevent in google. In my case however it turned out to be a really trivial and stupid mistake: I had AddModule lines for the both the PHP4 and PHP5 SO in my httpd.conf file. Please check your own httpd.conf file. If not that it could also be conflicting extensions.(apologies if this reaches the list twice - the first time I sent it, it didn't arrive within 12 hours)
Hi,
Recently I migrated the front-end of our bulletin board (running phpBB, patched against the recently highlight vulnerability) to a pair of servers running Fedora Core 3. I compiled Apache 1.3.33 and PHP 4.3.10 from source. The MySQL database is running on a separate machine.
This morning, the servers slowed down to the point that they were almost completely unresponsive. After a while I managed to SSH into the machines and saw that the httpd processes had grown to 35MB each and were using up all the swap and RAM on the machines (they have 1GB RAM, 1GB swap). I then set MaxClients to 30 and restarted Apache, but the slowdown happened again:
I then checked the error log and found this:
*** glibc detected *** double free or corruption: 0x097ec7e8 ***
