I too see a similar error message in the app logs, it would be great if someone posts the solution, even though there are support tickets opened.

In the logs shared by Shane and Karthik, both are just warnings which can be ignored.

 

In Shane's shared logs the BT count per node has exceeded the limit, and in Karthik shared logs it has got more sql calls than excepted and logged a message stating that it has reached limit.

Hi @Nawaz Ali.Mohammad 

 

WARN BoundsEnforcer - BoundsEnforcer for collection com.singularity.ee.agent.util.bounded.collections.BoundedConcurrentReferenceHashMap with service name TransactionMonitoringService and property name SqlCacheHolder-connectionVsZosSSID-limit has exceeded maximum size of 550 entries.

 

The warning message cannot be ignored as the agent stopped reporting and caused a false Alert to the Support team for an application being monitored.

 

There was an escalation and we need to ensure that the Agent reports seamlessly without loss of monitoring data.
