Re: [Dev] [BPS] Warning message from cluster when carrying out performance test
Hi,
This issue seems to be happening during various scenarios.
Those are
- Sometimes it occurs due to heap memory getting filled
- In some occasion it occurs when ever I increase the
max_connections variable in database. ( I changed the other
datasource.properties and bps.xml as well )
I will attach the log file next time when I encountered with this issue.
Regards,

Re: [Dev] [BPS] Warning message from cluster when carrying out performance test
Hi Firzhan,
It seems the hazelcast instance is dead when this exception is happening.
Can you enable logs for the hazelcast packages and clustering packages and
see what is happening when this exception occurs. There is a possibility
for this exception to occur when the server shutdown is happening due to
hazelcast being shutdown before the ode scheduler. However, it should not
happen at other times.
Also when using the cluster, make sure that ( total db connections
available ) ( bps thread pool size) * (number of nodes in cluster)
Regards
Nandika
