Hello,

I apologize if this email is getting resent, I can't find any confirmation =
that it was received. I am having difficulty trying to figure out why Couch=
Db is crashing from the crash report, and I was wondering if someone would =
be able to give me some feedback on what could be going wrong.

Here is my scenario: I have a Couch instance with over a million documents.=
 There is also continuous replication going on to and from another instance=
. Periodically, CouchDb crashes because of the crash report below. I increa=
sed the `max_dbs_open` and `max_connections` settings in the config, but th=
at didn't stop the crashing.

I was linked to this issue (http://mail-archives.apache.org/mod_mbox/couchd=
b-dev/201212.mbox/%3CCAHZBNKbhXinyJzbTZ14Ddi9_2jTu=3D9QjMFjSS+36_vnM80PPCw@=
mail.gmail.com%3E). Is that similar to the issue I am hitting? If so, it lo=
oks like the fix was merged into mochiweb, but the version that ships with =
CouchDb doesn't contain the fix.

Thanks!

Brendan Walker
