Failed over node

Couchbase Server
1

Community Edition 6.6.0 build 7909

I have 3 node cluster. Each node is running on 2 core 8GB Linux server. Once in a while (1-2 month) one of the nodes turns failed over by the other two. What I can read from the logs - after Compactor daemon quits unexpectedly on a failed node the node comes back healthy.
Is there any way to proactively prevent such events?
Can I schedule compactor service to run during lower load hours?
Thanks

I found Compactor schedule in Web Console Settings->Auto-Compaction. Will set Compactor to run off peak hours and see if it helps.
