I’ve encountered this from time to time and I cant seem to find the fix.
Usually when this error occur, I am seeing increasing number of connections being used while its connection is not being disconnected.
Here is a sample logs on mongo.
But I observed that this log below is its normal behaviour:
Another thing that I noticed before the error occur is that there are numerous "Unable to gather storage statistics for a slow operation due to lock aquire timeout"
At the first time I encountered this issue. We set MaxConnectionPoolSize = 200; then it occurred again. Any idea how to fix this?
