ActiveRecord::ConnectionTimeoutError about rapns

[j-mcnally]

The solution here was to add

ActiveRecord::ConnectionTimeoutError

to the ADAPTER_ERRORS in reconnectable.

Does this make anysense, without it the db wouldnt try the connection again

Yes, checking for ConnectionTimeoutError does make sense. Usually this error is a symptom of not having a large enough connection pool. What is the sum of all connections in your rapns_apps table?

i was afraid this was an issue, i have to set small DB_POOL size because we are wroking on heroku postgres_hobby which limits pool size to 20. Probably why I ran into this, while probably a bit slower, checking ConnectionTimeoutError seems to have resolved the symptoms.
