[Archivesspace_Users_Group] Intermittent Outages

[Alexander Duryee]

Our production instance of ASpace has been suffering from intermittent
outages for the past few weeks.  Roughly once or twice a day, the
application will go down for 1-5 minutes, then bring itself back up.
Perplexingly, this doesn't seem to impact the backend - for example, the
application went down during a reindex, but the reindex continued (and was
logged) during the outage.  However, API requests are dropped and the
frontend is inaccessible during the outage.

We haven't identified a cause for the outages (e.g. heavy traffic, lots of
database calls), as there's no consistent pattern.  There's nothing in
archivesspace.out to indicate any troubles.

Has anyone else experienced similar issues?  Is there another log that we
could refer to (e.g. ASpace's Apache instance) to diagnose the outages?

Thanks!
