Re: Segfault with error 4 in doveadm-server

Alexander and Aki,

thanks for your quick answers. It might be the best to compile a more recent version of dovecot. For some reason it seems unpossible to get a core dump and the error might be fixed in a recent version.

I set up dovecot on two servers with replication enabled. The replication is over a vpn connection. I get massive segfaults from doveadm-server every few minutes. dmesg: doveadm-server[30030]: segfault at 0 ip 0000557fa16d2e62 sp 00007ffdcaafec50 error 4 in doveadm-server[557fa16a3000+41000] [486397.225636] Code: 40 03 4c 8d 3c c3 48 8d 44 24 18 48 89 44 24 08 0f 1f 84 00 00 00 00 00 49 8b bc 24 60 01 00 00 e8 e3 2a 00 00 48 89 44 24 18 <48> 8b 13 48 8d 35 c4 8d 00 00 48 89 c7 e8 2c 2b 00 00 31 c0 c6 45 mail.err dovecot: doveadm: Fatal: master: service(doveadm): child 29507 killed with signal 11 (core dumps disabled) I am absolutely unaware of how I can come to the cause of this error. Can anyone give me a hint?

Configuration: # 2.2.13: /etc/dovecot/dovecot.conf

First, use a supported dovecot release. Please see

https://dovecot.org/list/dovecot/2018-August/112536.html

In case that's the Debian 8 version open a report with Debian.
