Hi!

signal 11 is defined in /usr/include/signal.h (or some header file included
from there, on my SuSE Linux it is found in /usr/include/asm/signal.h)
#define SIGSEGV 11
(Even though the numbers should be quite similar between UNIX variants.
So it seems, cleanup experienced a segmentation violation. Normally,
there should now be a core dump in /var/spool/postfix, that can be
analyzed with your preferred debugger.
If you don't have a core dump, you might have to set some ulimit value
I don't remember, typically, the (non-understandable) Linux-default for
the max coredump size is 0.
Once you have a core dump, you will easily find the reason for the segmentation
fault... And we would like to hear of it eventually.

Best regards,
        Lutz
