System runs well for a while and then the UI hangs. I believe it is when there is a task that runs longer than 12hrs.
Console.log contains multiple failures:
2021-06-02 09:10:48,432 WARN com.mchange.v2.resourcepool.BasicResourcePool$ScatteredAcquireTask@27983d8d -- Acquisition Attempt Failed!!! Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (30). Last acquisition attempt exception:
