although it seems to happen when the system is overloaded. In
total, I
have
5 processing constantly reading from and writing to the same
couchdb,
with a
resulting load average of about 3 and physical memory at it's
limit. I
get
the impression (though it's hard to reproduce) that this error
come at
the
moment the system is swapping some ram out to disk, making couchdb
run
into
some timeout while calculating a view.
Couchdb does stay online though, only crashing my app with an
unusable
result.
Can you check if couchdb actually stays alive or if it's getting
respawned by heart? The easiest way to test this is to run couchdb
with the command line without the init.d script.
Erlang closes the entire VM when it's unable to acquire memory. Ie,
if
malloc returns NULL, then the whole VM closes. The general idea being
that it'll just rely on heart to be restarted.
