Ubuntu 10.04 Desktop, i386
As soon as I configure a replication with a certain filter, couchdb crashes.
Your issue is the same as COUCHDB-1199 (I read the log file).
It is already fixed for the next maintenance release 1.1.1 and 1.2.0.
This filter is also crashing couchdb
This is my complete couchdb log. The last lines are there because I had to rename manually the _replicator database to bad_replicator, and put the default _replicator database back, so that I could start couchdb again and take a look at what was being stored in the _replicator database before crashing.
