Replicator: net.jini.core.lease.UnknownLeaseException

Hi

I see lot of following warning in logs. I would like to know what might be happening. I use 2 partitioned sync to backup topology.

I assume this is happening b'casue object lease has expired on backup before the primary propogates same to backup(notification might have delayed due to GC). Correct if I am wrong.

In theory this might be the problem. Do you see this message at the backup ?
Do you have objects with a short lease? If so , try to increase the lease time to resolve this.

Any idea why you have such long GS pauses?

Thanks for the reply Shay

I see these warning on both primary and backup.
I don't think we have noticeable long pause times. Containers been running for 30 days and it took only 42 seconds as GC time.
As leases can be set in milliseconds I was assuming even a milliseconds makes a difference.

Can you explain more what kind of scenarios may cause these warnings.

It does not make sense having “net.jini.core.lease.UnknownLeaseException. Failed to cancel Entry lease” from both the primary and the backup. Std66_container2_1:Std66 seems to be a backup. Do you have the same coming from the primary space?

Are you sure the backups are backup only or you have these as replica and clients accessing these spaces and performing write operations? Are you sure you have sync replication or is it async replication? Getting “This entry might be already expired or canceled.” is very rate with sync replication. It might happen only with async replication mode.
