This doesnt seem to be related to the mmap problem
The only errors I got on cyrus log when it happened were a bunch of this:
Apr 10 16:35:03 cyrus-fe1 cyrus/lmtp[30983]: mupdate-client: connect(10.1.5.101): Connection timed out
This time I have strace and gdb logs. Im sending attached the last 1000 lines of the mupdate process strace, the last 1000 of the mupdate thread strace and the gdb trace I managed to extract from the core dump.
Note that strace was configured to not log futex calls.
