Hello everybody,
i tried to debug imap sessions with the rawlog feature and rawlog
creates files but when i try to dump them doveadm tells me
[...] Error: zlib.read((file)): unexpected EOF at [...].
I looked at syslog files and i see, that rawlog gets
terminated with a segfault, e.g.:
segfault at 10 ip 00007ff6da362596 sp 00007fffe725a080 error 4 in
libdovecot.so.0.0.0[7ff6da2a4000+122000]
Is there a way to debug why rawlog ist terminated? I haven't found
anything.I would be very thankful, if somebody could give a hint.
My system is:
# 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf

# OS: Linux 2.6.32-696.3.1.el6.x86_64 x86_64 CentOS release 6.9 (Final) ext4
