double free or corruption

[whplus]

I am getting the following error on /usr/local/cpanel/logs/error_log.

*** glibc detected *** /var/cpanel/3rdparty/bin/php: double free or corruption (!prev): 0x0a24bb60 ***

I think this error due to corrupted cpanel's php, so I recompiled cpanel's php but still get the same.

I am using cPanel 11.23.3-S25971, RHEL 5.2 on Quad Core Xeon 5430 w/ 4GB RAM.

If you have any suggestions please let me know. Thank you.

Hello,

I am getting similar error_log errors on three different VPS, always generated after accessing PHPMyAdmin from CPanel interface on any user account. It doesn't seem to be affecting MySQL or PHPMyAdmin functionality.

This is a message on a VPS CENTOS Enterprise 4.6 i686 on virtuozzo:

*** glibc detected *** double free or corruption (!prev): 0x0871b450 ***

And this one, on a second VPS with same OS:

*** glibc detected *** corrupted double-linked list: 0x0873b120 ***

On a VPS CENTOS Enterprise 5.2 i686 on xen these messages are much larger:

*** glibc detected *** /var/cpanel/3rdparty/bin/php: double free or corruption (out): 0x09a846a0 ***

... and fifty more lines of "Memory map".

My CPanel version is 11.23.4-R26138 on the three servers, but it began to happen several updates ago.
