    Hi @malayarasanm, this window size 0 condition generally means your application as a whole is unresponsive. The thread that processes incoming messages and sends acknowledgements (the context thread) is blocked. The Solace API can't read any more messages from the network and isn't sending any acknowledgements back.
    Do you have the output from any profiling tools for your application, such as top? Is that showing your CPU is at 100%? Is your application producing any output? Is it stuck waiting for something else to happen, like obtain a lock to a database? Do you have any heart beat mechanism in your application? I can see that it has received 195 messages successfully.
