Error closing YF application

HI,

We have found an issue while stopping the YF application.


YF:2015-01-21 00:18:27: INFO (DBConnectionManager:shutdown) - DBConnectionManager shutting down
YF:2015-01-21 00:18:27: INFO (DBConnectionManager:shutdown) - Shutting down connection pool for sourceId: 0
YF:2015-01-21 00:19:20:ERROR (DBConnectionManager:shutdown) - Error closing connection pool: java.lang.Exception: Connection pool was not cleanly shut down - connections are still checked out
java.lang.Exception: Connection pool was not cleanly shut down - connections are still checked out

Why is this error occurring?

Moreover YF application was very slow and CPU utlization went High.In the logs there was no such major error that could bring down the speed of the application.

Later we decided to a restart and we found the above error.

We have checked all the connection pool as well.(primary and secondary with max 15)

Is it related to the slowness? please advise what could be done to avoid this in future.

Thanks,
Mala
Hi Mala,

You usually see this message when a connection was still marked as open, so it gives an error to say the connection was dropped.
Nothing to worry about, as the connection is forcibly closed and won't affect anything as Yellowfin is shutdown.

It's nothing to worry about and will probably see this message in most YF instances.
It will not affect performance.

Please let me know if you have any other questions on this.

Regards,
David
