Description
Description:
When two GS engines are running on two different machines and the file poller services is in the fault tolerant mode, the underlying RV communication issues can cause issues with the file poller services.
Symptoms:
Files can be polled and picked up a number of times within the polling interval. For example, if the polling interval if 1 minute, instead of polling the file once every 1 minute, the file poller would poll 6 times. Monitoring the network we could see primary file poller service A getting deactivated, the secondary service B turning into an activated state ( turning to primary) but the original primary poller service A is still polling the folder.
Cause:
When a fault tolerant switch happens between the file poller service, the secondary poller service assumes that the primary poller service has exited and turns into the primary. Under certain conditions, the secondary poller service becomes the primary, even though the primary service did not exit completely. Both will start to poll the same files.
