2.17.1 Fatal: master: service(doveadm): child 43879 killed with signal 6 (core dumped)
Hi, my dovecot 2.17.1 instance is crashing a lot.
Quick question: The coredump should contain some private data, am I
correct ? Assuming so, should it be posted on a public maillist?
Panic: file dsync-ibc.c: line 166 (dsync_ibc_send_mail_request):
assertion failed: (request->guid != NULL || request->uid != 0)
...
Fatal: master: service(doveadm): child 43879 killed with signal 6 (core dumped)
Using gdb/bt over the coredump I get:
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `dovecot/doveadm-server'.
Program terminated with signal SIGABRT, Aborted.
