Hi.
We're using JMS to do Pub/Sub and periodically we run into NamingExceptions while performing a lookup for a topic. We are using FileSystem as Context and we're trying to publish 10K messages using 20 concurrent publishing threads. It is not specific to one topic (it periodically happens for all 4 topics that we are trying to publish). I've checked the bindings file and the entries do exist. We are also able to publish a majority of the messages but on occassion, we get these NamingExceptions.
I am questioning if there's a load issue related to retrieving mq objects through FSContext. We are currently in the processing of testing using a high-load, all to be published to one topic to reproduce the issue.
I have attached the exception below. Any ideas?
Thanks -- Selena
