Try out some of the diagnostic steps here. Is it always the vlans_fdb table? You can probably turn off polling that data for now so polling keeps working.
https://dev.mysql.com/doc/refman/5.6/en/innodb-deadlocks-handling.html * At any time, issue SHOW ENGINE INNODB STATUS<https://dev.mysql.com/doc/refman/5.6/en/show-engine.html> to determine the cause of the most recent deadlock. That can help you to tune your application to avoid deadlocks. * If frequent deadlock warnings cause concern, collect more extensive debugging information by enabling the innodb_print_all_deadlocks<https://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_print_all_deadlocks> variable. Information about each deadlock, not just the latest one, is recorded in the MySQL error log<https://dev.mysql.com/doc/refman/5.6/en/glossary.html#glos_error_log>. Disable this option when you are finished debugging. ________________________________ From: Thomas Stather via observium <observium@lists.observium.org> Sent: Friday, October 28, 2022 12:53:01 AM To: observ...@observium.org Cc: Adam Armstrong; Thomas Stather Subject: [Observium] Re: Lots of errors "Deadlock found when trying to get Hi We have 207 devices (network, servers, ups etc.) 6709 ports 2841 sensors The problem is still not fixed.
