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 as a web server.

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.

Try
ldd /usr/sbin/httpd |grep found.
Anything found is a missing library. You should net get any message.

I would also restore a backup and check them with md5sum
