Running a sharded cluster, consisting of 2 shards. We are using 2 mongos processes.
MONGO ACCESS PROFILE:
We start a job that runs for about an hour and half and makes a lot of reads to mongo (no writes). reads are of the order a several thousand per seconds). I observe that the errors occur at the beginning of the job rather than being spread over the entire time period that the job runs
We are running 2x mongos processes. I'm seeing errors like the following:
