Subject Re: Please Urgent !!! CouchDB crashed on Windows
Date Sat, 11 Sep 2010 12:51:12 GMT

I've had CouchDB in production on windows for almost a year now, for
non-critical services. At first there were problems with replication
and compaction.

Since  March I've used 0.11, patched with windows fix form Damien Katz
and Mark Hammond. Haven't run into problems with that. Some essential
services (that tolerate a little downtime, if necessary) are now
running on it. One DB has millions of documents and tens of GB of
data. One is such that documents are updated a lot and the db needs to
be compacted regularly.

I've had 1.0.1 (mhammond) on a few laptops for development since it
was released. It's running as a service and has worked so reliably
that I haven't had to pay any attention to it. It's always been there
when I've needed it. The usage has been light.

My plan for upgrading to 1.0.N is to wait for the next release of
erlang, then to test thoroughly and only then upgrade.

Unfortunately I don't have much advise in addition to that already
given. I've never have a db or view file corrupted. Try to provide
more detailed information about the use case and the conditions which
lead to crashing. If possible, see if the problem also occurs on
another machine.
