malloc(): memory corruption

Hi, all!

I run httpd with our site and get in error_log:

*** glibc detected *** malloc(): memory corruption:
0x000000552b92eda0 ***
[Wed Dec 27 06:45:16 2006] [notice] child pid 3646 exit
signal Aborted (6)

for 50% query.

This is present on 4 servers. I don't think about hardware
memory problem.

What I can do for fix it?

Thanks!

What additional software is running with httpd? php, tomcat,
java applets, etc?
Is there a common feature among requests which draw this
error?

Need to find out what's causing it first. Then we can work
on fixing it.

This is x86_64 version.
mod_perl-1.99_16-4.centos4
libapreq2-2.02-dev selfinstalled
mod_limitipconn-0.22-0 selfinstalled
mod_rpaf-0.5-0 selfinstalled

No. This is one request runing many time.

Okay, what is the request that's running which causes the
error?
For the self-installed software, is this installed via rpm
or source
build? If rpm, is it built for RHEL4/CentOS specifically or
is it
built for something else?

If it's source build... BAD ADMIN... NO COOKIE!   :-P

Get rid of this fluff, can you still reproduce the issue ?
if you can, 
open a bug report at http://bugs.centos.org/
along with a `rpm -qa` and 
details of the hardware.

Reason of this error is libapreq2-2.02-dev. Sorry, but I not
have time 
for detail investigate.

I try mod_perl2+libapreq2 last version and not detect this
problems. But 
for my soft need mod_perl 1.99+libapreq < 2.04-dev. :(

I reinstall OS on 32-bit version now. :(

Having just spent quite a bit of time wrestling with
mod_perl, I might have 
some insight into this.

the mod_perl sipped with CentOS is 1.99, but with a
subversion BEFORE a major 
API shift that was standardized for mod_perl 2.0.  Your
libapreq2-2.02 is 
probably trying to utilize the new API and running into
problems.

You could either:
A) build or acquire RPMs for a true mod_perl 2.0 environment
(I didn't have 
much luck getting my target app to run when doing this, but
that could have 
been my particular app), or
B) wait for CentOS 5 and use that (if you are comfortable
with using the 
initial release).

I would suggest using CentOS 5 if you require the features
of mod_perl 2.0 and 
above.  If something has a problem, it will most likely be
fixed by Redhat, 
so you aren't responsible for tracking down small
inconsistencies with self 
installed packages.

If you have more problems with this, you will probably be
better off posting 
to the CentOS users list, since this is almost definitely a
conflict with a 
self installed package and not a core component failure/bug.

The RT repository (documented at http://wiki.cento
s.org/Repositories)
has mod_perl 2.x already built. Might be easier to just use
those
packages assuming that's related to the issue.
