[Rspamd-Users] rspamd: *** stack smashing detected ***: rspamd: controller process (localhost:11334) terminated

[Thomas Plant]

Hello,

found this message in /var/log/messages:

Apr 24 09:24:05 rspamd rspamd: *** stack smashing detected ***: rspamd:
controller process (localhost:11334) terminated

Anyone seen such a message in the logs? In rspamd.log I see at the same
time the following:

Rspamd is  latest 1.9.2 on CentOS 7

It seems to me it happened when i clicked in the gui on 'Symbols'.
Attached a screenshot of the gui with error. After clicking around in
the other menus the editing/displaying of 'symbols' worked again, think
'cause of restarting the terminated rspamd controller process.

Greetings,
Thomas
