You should try upgrading to 2.5.4 (or at minimum to 2.5.3 Security
Update 1):

To quote from the 2.5.3 Security Update 1 release notes:

"The Superserver and Superclassic servers could crash with a
segmentation fault caused by a malformed network packet, opening a
vulnerability. It does not affect the Classic server."

Given the seg fault this might be the problem (although not 100% sure).

However I'd suggest upgrading 2.5.4, as several other server crashes
have been fixed in that version.
