Spider monkey was installed from 1.7.0 source.

Don't think so:

Is there any way to get more visibility into the problem? Debug logging? 



Hmm, debug logging probably won't get you much beyond the erlang
traceback. IIRC, there's no debug option for couchjs.

AFAICT without adding debug statements to your setup is that the error
is happening when couch_query_server sends ["reset"] to the couchjs
process. From my initial poking through the various bits it looks like
couchjs is crashing as opposed to exiting cleanly. A quick way to
diagnose this is to start up couchdb, get a couchjs process started,
attach to it using gdb, and then trigger the error to see if you can
get a traceback. That sounds not quick now that I typed it out.
Anyway, hopefully its straight forward. Also, if it is exiting
cleanly, you could set a break on the return line and try and get a
traceback of what lead to the exit.

Also, how did you install spidermonkey exactly, was it a manual build
or from yum or an rpm?

Ran your suggestion..

[r...@rhel4-dell 0.9.0]# su - couchdb
[couc...@rhel4-dell ~]$ curl http://127.0.0.1:5984/_config/query_servers
{"javascript":"/usr/local/bin/couchjs /usr/local/share/couchdb/
server/main.js"}
[couc...@rhel4-dell ~]$ /usr/local/bin/couchjs /usr/local/share/
couchdb/server/main.js
["reset"]
true

The test suite still returns the same errors.


Maybe your LD_LIBRARY PATH is hosed for the CouchDB user and the
couchjs process
can't find the libs (libjs.so, libcurl.so) it links?

Cheers

Hi all,
I have been trying to run couch 0.9 on RHEL 4 and I am getting
errors when trying to run the test suite. I installed spider monkey 
1.7.0 and also a newer version of curl since couchdb configure
script
complained that I needed curl >= 7.15.5.  I tried almost
everything I
could think of - but I can't get rid of these errors!
I don't have the ability to reproduce this setup currently, but the error message you see looks like the couchjs process isn't launching 

Try running this command:

curl http://127.0.0.1:5984/_config/query_servers

And then run the command quoted in the output. When it's working
properly, you should be able to type:

["reset"]

and get the response:

true


Here is the output when I run the basic test in the test suite:
Exception raised:
{"error":"{bad_return_value,{os_process_error,{exit_status,
127}}}","reason":"{gen_server,call,[couch_query_servers,
{get_proc,<<\"javascript\">>}]}"}

Reduce fails with the following exception:
Exception raised:
{"error":"badmatch","reason":"{{bad_return_value, {os_process_error, 
{exit_status,127}}},\n
{gen_server,call,[couch_query_servers,{get_proc,<<\"javascript
\">>}]}}"}

and a lot of tests are failing.

Here are the last few lines from the couch.log file.
