Hi,
We are running Ignition Version 8.1.7 and have just had an issue with all the Transaction Groups failing to update at the ‘Next execution’ time.
Info at time of fault;
Ignition Version: 8.1.7 (Licensed)
Module Version: 10.1.7 (SQL-Bridge)
Uptime: 3 Months
CPU: around 4%
Mem usage: Around 6 Gb
Devices: 193, 141 Running (Normal), Others offline (Normal).
Transaction Groups: 440, 411 Running, Others disabled, No Errors
Transaction Status: Running (All that are enabled)
Execution Scheduling: Timer (Most 5 to 10 seconds)
Trigger: Run-Always Expression (expression checking for 2 tags to be true)
Next execution time: 10 or 5 seconds after the ‘Last execution’ time (depending on the group)
Database: Online and operational.
Other: No Clock Drift.
Tried;
Pause / Un-pause - Status changed to pause and back to run, group(s) did not execute.
Disabled / Enabled transaction - Status would then change to ‘Unknown, waiting for execution’, ‘Run-always’ trigger would stop updating, Last execution would not update, Transaction would show the ‘?’ mark.
Restarted Sql-Bridge (web interface) - All transaction changed to ‘Unknown, waiting for execution’ last execution would stay blank, Run-Always Expression not updating. No errors shown, No information in Logs, Next execution would show the expected timer after the module restarted. Thread dump looked good.
Restarted Server (gwcmd --restart) - Transaction Groups restarted without issue.
This is the first time I have found this issue, my team member has had the odd issue and found the disable / enable would fix.
What other options would I have to restart the group(s) with out restarting the server?
Has anyone else had a similar issue?
Regards
Matt.
