OS process timed out?
Hi,
I'm running couchdb on a small EC2 instance and I've been getting a
lot of these "OS Process timed out" errors when querying views. The
view is returning a set of word counts for a document. The view runs
fine on my 2 yr old macbook pro.
Im using Ubuntu 8.10 intrepid AMI built by Eric Hammond from http://alestic.com
.
The erlang version on EC2 is:
Erlang (BEAM) emulator version 5.6.3 [source] [async-threads:0]
[kernel-poll:false]
There are only 232 documents in the database. It fails 50% of the
time. Any thoughts on debugging? My erlang skills are n00b at the
moment.
In the log file, the query is like this when it's successful:
[Tue, 21 Jul 2009 23:57:45 GMT] [info] [<0.2834.0>] 127.0.0.1 - -

%7D%5D&group=true 200
but like this when it gives an error:
