Cpanel Error log messages

Hello,

noticed this today in the cpanel /usr/local/cpanel/error_log:

*** glibc detected *** free(): invalid next size (fast): 0x08bf2340 ***
panic: malloc.
*** glibc detected *** free(): invalid pointer: 0x0890e3d0 ***
*** glibc detected *** free(): invalid next size (fast): 0x08c080f8 ***
*** glibc detected *** free(): invalid next size (fast): 0x08c085c0 ***
Attempt to free unreferenced scalar during global destruction.

never noticed this before and was wondering if something to be concerned about or what maybe causing the error.

TIA,
Mickalo
