Have not yet been able to reproduce this locally but from code reading wondering if an onPurgeError hook in the test code would be helpful alongside the onPurge hook here: https://github.com/apache/lucene/blob/releases/lucene/10.1.0/lucene/monitor/src/test/org/apache/lucene/monitor/TestMonitorReadonly.java#L212
