Problem with Kernal Update

We are recieveing the following error, which is causing the server to lock-up.

These are the error messages we are seeing in the apache error_log:

*** glibc detected *** corrupted double-linked list: 0xcc100048 ***
*** glibc detected *** double free or corruption (!prev): 0x56d60df0 ***
*** glibc detected *** corrupted double-linked list: 0x56bd5270 ***
*** glibc detected *** double free or corruption (!prev): 0x56bf1ba0 ***

On Friday the system had some patches installed, and the problem may be related to these. The installed patches that seem particularly relevant to this problem would be the kernel update:

New version Previous version
kernel 2.6.9-22.0.2.EL 2.6.9-22.0.1.EL
kernel-devel 2.6.9-22.0.2.EL 2.6.9-22.0.1.EL
kernel-smp 2.6.9-22.0.2.EL 2.6.9-22.0.1.EL

glibc on this system was not updated.

The system is currently running on kernel-smp-2.6.9-22.0.2.EL, as indicated by the output below:

[xxxxxx@eqd1 texis]$ uname -a
Linux eqd1.hants.gov.uk 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:11:56 EST 2006 x86_64 x86_64 x86_64 GNU/Linu

Do you know if there are any compatability problems between webinator and this version of the kernal

No known problems with kernel 2.6. Messages in apache's error log could be coming from apache itself or any program it spawns.

I wouldn't expect any errors in texis/webinator to cause system lockups.
