Camel JPA Thread Hung
Hi All,I have created one route which has JPA component to poll the records
from DB periodically. it is working good. I hope each route has one worker
thread. if DB is down or any N/W issue for minute, route is not working as
expected. application is running.( it is not polling records from DB even
after DB or N/W is up ). I think worker thread got hung and route is not
working. please anybody help me to fix this issue.How to avoid this worker
thread hung ?How to restart the worker thread once N/W or DB is up ?

Hi
could you provide the route you defined with the parameters defined?

I would start look at your jdbc driver and connection pooling how that
is configured to have a way of "heal" broken connections
