2.2.25 dumps core with "Panic: file imap-client.c: line 837 (client_check_command_hangs): assertion failed: (client->io != NULL)"
Hello,
Dovecot 2.2.25 OS: Solaris 11 (SunOS 5.11 11.3 i86pc i386 i86pc) Virtualization: VMware Filesystem: ZFS active users: ~4000
About once a day Dovecot crashes with "Panic: file imap-client.c: line 837 (client_check_command_hangs): assertion failed: (client->io != NULL)"
The log shows in each case:
Aug 29 12:59:00 surz113 dovecot: [ID 583609 mail.crit] imap(username): Panic: file imap-client.c: line 837 (client_check_command_hangs): assertion failed: (client->io != NULL) Aug 29 12:59:00 surz113 dovecot: [ID 583609 mail.error] imap(username): Error: Raw backtrace: 0xffff80ffb6f3d88d -> 0xffff80ffb6f6ae82 -> 0x41eba0 -> 0x41ecf3 -> 0xffff80ffb6f5d248 -> 0xffff80ffb6f50d2f -> 0xffff80ffb6f519e0 -> 0xffff80ffb6f50dce -> 0xffff80ffb6f50f90 -> 0xffff80ffb6ee3ebb -> 0x42f169 -> 0x41292c Aug 29 12:59:00 surz113 dovecot: [ID 583609 mail.crit] imap(username): Fatal: master: service(imap): child 1461 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })
It happens with different users, all with mailbox-sizes of 9 to 17 GByte. The server stops completely for all users with this Panic and is then restarted automatically from Solaris Service Management.
Find attached the output of 'doveconf -n'.
Please let me know, if you need any more infos.
Thanks for any help on this issue, Andreas, postmaster@uni-marburg.de

I fixed one such crash in git master branch, but it was never in 2.2.25..
Find attached the output of 'doveconf -n'. .. # 2.2.25 (f5ac02c): /etc/opt/csw/dovecot/dovecot.conf
What is this version? 2.2.25 release had 7be1766. I can't find any such commit hash from git.
Hello Timo,
Find attached the output of 'doveconf -n'. .. # 2.2.25 (f5ac02c): /etc/opt/csw/dovecot/dovecot.conf
What is this version? 2.2.25 release had 7be1766. I can't find any such commit hash from git.
This is the dovecot-package from OpenCSW: https://www.opencsw.org/packages/CSWdovecot/ I have no idea, if these guys apply any changes to the code, but I'll ask the maintainer.
