SA-15871

Summary

Hazelcast clustering errors are observed during server startup in the PegaRULES logfile.

Error Messages

Interfaces is disabled, trying to pick one address from TCP-IP config addresses: [IP]

...Could not find a match for URL

Steps to Reproduce

This occurs when Pega starts up a single node system. The system is isolated and cannot access the IP address stated in the error message.

Root Cause

An erroneous or stale IP address was in the py_sys_statusnodes database table. It was in py_sys_statusnodes because there had, at one time, been a deployment of this system at this location before being undeployed.

Due to firewall or other network settings, hazelcast could not reach the IP address in the error message to determine that the node is offline and instead throws the observed network error.
 

Resolution

TRUNCATE py_sys_statusnodes to resolve this issue. This removes the record of the non-existant node(s) from the database and hazelcast does not search for them during startup.

Pega rebuilds the py_sys_statusnodes automaticall, with the nodes that are in use.
