Solace Client running out of memory with multiple consumers

Sateesh Kommineni

Hi,
We are using Solace JMS to read the Data from a JMS Queue and in order to keep up with the rate at which data is produced we are using 50 Consumers in worker threads and this is causing OutoFMemory Issue.
Looks like as soon as we are creating the session and connection it is getting disconnected and the client/consumer is constantly trying to create the connection ( we have the logic to recover and try to reconnect and establish a session if the consumer gets disconnected). We get the data for a while and then we eventually run into OutOfMemory heap error.
We are running the client with 30GB of memory.
Here are the errors we are seeing in the logs.

what are your Java JVM settings for the client app? It's running out of heap. Have you increased that?
