All our webservers are down! RESPAWN_TIMEOUT=1 doesn't work and we can't to apply an attached patch cause couchdb 1.0.3 has another code lines. Waiting for your response. > CouchDB crashes by Erlang Heartbeat Runtime System > -------------------------------------------------- > > Key: COUCHDB-1052 > URL: https://issues.apache.org/jira/browse/COUCHDB-1052 > Project: CouchDB > Issue Type: Improvement > Components: Infrastructure > Affects Versions: 0.10.1, 1.0.1 > Environment: Solaris 10 > Reporter: Nicolas Maupu > Attachments: couchdb-bin-1.0.1.diff > > Original Estimate: 2h > Remaining Estimate: 2h > > Hello, > We have several couchdb in our production environment (starting from 0.10.1 and upgraded to 1.0.1). Some instances began to crash several times a day. > After research (I am not aware of all erlang tips and tricks), I found that the problem was caused by erlang heartbeat runtime system (http://www.erlang.org/doc/man/heart.html). > For some reasons (it seems to be a problem with system clock), this heartbeat process sends a signal to main erlang process to trigger HEARTBEAT_COMMAND. > The command configured by couchdb startup script is to call 'bin/couchdb -k' which kill server ... > I don't know if this is wanted or not but is Erlang heartbeat system provided to restart a service if this one crash ? > I patched mine to restart process gracefully but I would like to know if this is a feature or a bug : next time I upgrade, I will have to patch again. > My patch is a little bit specific to my architecture so I did not provide it.
