Hello Janos,
happened Sa->So this time.
Logs (piler-smtp as compiled out of smtpsegv.tar.gz source code) see
below, SIGSEGV follows right after free(session) done.
It is also interesting to see that the piler daemon finishes processing
a message 2 whole minutes after the smtp process has already segfaulted
and and stopped supplying any new messages.
Thanks, Patrick
