Hello,

On my Sinatra App I'm getting random errors (it does not occur all the time) to a mongodb replica set when trying to write on the DB.
The error is the following:
No server is available matching preference: #<Mongo::ServerSelector::Primary:0x25372200 tag_sets=[] server_selection_timeout=30 local_threshold=0.015>

Anyone can help on how to avoid this? Could this be related with the connection pool size, should it be higher?

My mongoid.yml has the following options:

options:
connect_timeout: 15
read:
mode: :secondary
max_pool_size: 500
replica_set: newAnalyticsReplset
