One shard consumes higher memory


According to MongoDB memory utilization in cluster environment.
In our environment has 3 config nodes and 3 shard nodes.
We found Node4 in Shard nodes consume memory higher than aside nodes (Node5 and Node6 but Database Active on Node5).

Could you please help us to check which command to review which thing drain memory from non active node?

Best regards,

Hi @Jumphol_Buntuek,

Welcome to MongoDB community!

Best way to clear memory of a secondary is to reboot it.

However, to understand what consume memory you will need profiling tools (ops manager/mongotop) and best is to have a support engineer from Mongo to analyse it.

However, this is done via a support subscription and not through this community forum.
