View compaction error

Couchbase Server
1

Hi,

On one node out of 4 in a cluster, we’re getting this error and its compaction process just keeps restarting itself. Has anybody seen this before? This is on Couchbase 5.5.4

Compactor for view `esplorio.core/_design/achievements` (pid [{type,view},
                                                              {name,

We found another crash report under reports.log but so far nothing else. Any help or pointer in the right direction would be much appreciated
