glibc detected errors

[decodeweb]

Hi there,
Apologies if this is the wrong place to post but I'm having some real problems with some errors on a Redhat box running apache 2.2.3.

I'm getting these errors randomly in the error logs, and I don't know where to start looking:-

*** glibc detected *** /usr/sbin/httpd: free(): invalid pointer: 0x00002b0af1dda3f0 ***
*** glibc detected *** /usr/sbin/httpd: double free or corruption (out): 0x00002b0af208b1c0 ***
*** glibc detected *** /usr/sbin/httpd: munmap_chunk(): invalid pointer: 0x00002b0af1f056e0 ***

Then a ======= Backtrace: ========= and a ======= Memory map: ========.

There are no other errors in the logs? - apache stops running and needs restarting.

This is a standard Redhat Enterprise Linux 5 box running apache 2.2.3 and the relevant MYSQL / PHP modules + eAccelerator.

Any help at all is appreciated?
Cheers.

Looks like a major memory-pointer problem...

Review the "history" of this Apache install, and the install of glibc (if added separately). Without that info, I can't say much that would be useful.

Also try searching for that exact/complete "double free or corruption" error message; Sometimes others will be having the same problem.

Or try to find the "authors" of that library and see if they have a Web site or forum specific to it.
