edge postgres server and edge qpid server dead due to REST - ExceptionMapper.toResponse() : Error occurred : null

[aryapr2012]

I'm using 5 node installation. In my analytics slave, edge postgres and edge qpid is dead. While restarting it shows running but goes dead immediately. The system log for both postgres and qpid shows as mentioned below:

2019-01-22 06:00:20,526 qtp1355887174-26 WARN REST - APIRegistry.locateSubResource() : No match found for request path /server/metrics/

Kindly suggest what could be wrong in this case.
