Warning cannot communicate with Indexer process while updating index mutations

Hi Team,
We have the couchbase server with version 6.5.1. Here whenever some update happens, indexer is becoming unresponsive and throwing the below warning:
“Warning cannot communicate with the Indexer process”.
And after waiting for few mins, its becoming normal. What will be the possible cause for this?

Hi @pruthvi ,

To know the exact reason for this behaviour, requesting for cbcollect logs.


@pruthvi Would be great if you can share the cbcollect logs for us to analyse. Thank you!

Hi Team,

The issue got resolved after dropping one index. The array field which was indexed had millions of data. So every time, when update happened, indexing was taking more time. Thanks for all your responses.
