I got a core file this morning. opening it with gdb I get this: (gdb) core imap.core Core was generated by `dovecot/imap'. Program terminated with signal 6, Aborted. #0 0x0000000011c1347a in ?? () (gdb) bt #0 0x0000000011c1347a in ?? () #1 0x0000000011c13444 in ?? () #2 0x0000000000018dee in ?? () #3 0x306db139575f3b0d in ?? () #4 0x00007fffffffc144 in ?? () #5 0x0000000000000000 in ?? () Doesn't look clean at all. let me know if I should upload the file somewhere.
