Hi,
I using bigcouch and ran into a purge problem very similar to that purge
problem posted back on May 3, 2010 with the same subject title. I'm wondering
if the 'bug' that Chris referred to has been fixed.
In my case, I have a bigcouch db with the standard 8 shards and 3 replicas
each. I issued a purge to one of the deleted document in one of the replica as
follows:
> curl -d '{"kai_test1" : ["28-c3e23a0804e4a083e34e433037dfecf9" ] }' -H
> "Content-Type: application/json" -X POST
> http://172.26.172.20:5986/shards%2F80000000-9fffffff%2Fkai_testdb.1320702717/_purge
and got:
{"error":"{{badarity,{#Fun<couch_db_updater.19.85972910>,\n

Inspecting the log file I found:

Any idea why this is still happening?
