Wildfly Arjuna "Periodic Recovery" logs
I recently started receiving an excess of these logs and I'm not certain how to address them...
The logs:

My environment can be summarized as follows:
- 2x virtual nodes running Wildfly 16
- HA Cluster using domain
- 2x non-XA datasources (postgresql)
This is a lab environment, so there's no excess of traffic. The logs began to appear when I added a second ear to the servers. The new ear is a Clustered Singleton and runs a scheduled job service that queries for specific logs and if they're found uses RMI (remote interface) to the other ear in the application server (hence the reference to http-remoting on the loopback).
I guess I'm curious in general about these messages because it seems like a transaction is failing that it's attempting to recover. It has appeared that some of the scheduled job results are delayed, but I could be wrong there and I haven't gathered any metrics to know that for certain. If these are nothing to be concerned over, how would I go about suppressing them?
