[BUG] dovecot 2.3.0 - service(lmtp) killed with signal 11 when user is overquota
Hi,
I'm using dovecot 2.3.0 installed on a new CentOS 7.4 with rpm from
Dovecot repo. When I use LMTP to deliver an email to an overquota user,
lmtp service hangs with a segfault:
Jan 17 13:39:45 server-02.example.com kernel: lmtp[5099]: segfault at 0
ip 0000563599e372c2 sp 00007ffeaa4fdc80 error 4 in lmtp[563599e31000+b000]
Jan 17 13:39:45 server-02.example.com dovecot[5089]: lmtp(5099): Fatal:
master: service(lmtp): child 5099 killed with signal 11 (core dumped)
If I try to deliver a mail with 'dovecot-lda' on the same overquota
user, email was rejected, as expected:
Jan 17 13:38:26 server-02.example.com dovecot[6773]:
lda(USERNAME)<6773><ZbQDO8FDX1p1GgAASpDaHg>: Debug: Mailbox stdin:

If user is no more overquota, LTMP delivery works:

Attached my dovecot configuration and a backtrace from gdb.
Thanks,
