PMM-QAN MongoDB - Errors - Explain plan not working

Hi @Ivan_Groenewold/Team

We are using PMM2 client version 2.29.1
PMM Server version 2.28.0

Currently, I am seeing the below errors with respect to pmm-agent service on the monitored mongoDB Instances.

Error 1:

couldn’t add document to aggregator agentID=/agent_id/5f4075d5-c97e-47a5-b042-3ae28084cbad component=agent-builtin type=qan_mongodb_profiler_agent

Error 2:

incomplete read of message header: context deadline exceeded: cannot explain this type of query. component=actions-runner id=/action_id/0577e31a-81d7-4acc-9220-98c49275b02c type=mongodb-explain
I see that the mongodb_exporter and mongodb_profiler_agent are in running state.

I am seeing these errors very often and I had to restart pmm-agent service to fix.
Even after the restart, the errors get appeared again after 1-2 hours.

How can we avoid these errors? Please help me out.

Thank you,
Kiran
