Transaction Group SQL Insert delayed after end of DST

We’ve got a transaction group triggering a stored procedure to ultimately insert a record into a SQL table.
This has been working fine until after the daylight savings time this past weekend. It seems like the transactions get hung and after a period of time (1 to 5 minutes) any transactions that had been triggered will all process at the same time. We haven’t been able to find anything in the logs that would point to an issue. Rebooting our Ignition server seemed to correct the issue. Is this a known issue or something that we have to do differently to handle DST changes? We are running Ignition v7.9.10 with SQL Server 2014.
