doveadm backup abort in imapc-client.c
by Evan Klitzke 01 Oct '18

I am using Dovecot 2.2.36 and I am trying to use doveadm backup to migrate email from Gmail to Dovecot. When I run doveadm backup, it goes for a while and then eventually hits an assertion error (I've tried this a few times now and it happens reliably). The assertion failure looks like this: dsync(evan(a)eklitzke.org): Panic: file imapc-client.c: line 179 (imapc_client_run_pre): assertion failed: (client->ioloop == NULL) The last few lines of log output before the crash look like this: https://gist.github.com/eklitzke/9a0dd77c44a6ee33e812f85d5773c24c The GDB backtrace when the program panics looks like this: https://gist.github.com/eklitzke/6b311474b08b546c462e0444c5cf479b The output of "dovecot --version" prints "2.2.36 (1f10bfa63)" and I'm using the version provided by Fedora's dovecot-2.2.36-1.fc28.src.rpm package. Is there any other information I can provide to assist in debugging? I could provide a core dump provided there was a way to scrub my IMAP credentials. -- Evan Klitzke pgp: 0x157EFCACBC648422 e: evan(a)eklitzke.org w: https://eklitzke.org
