RE: R Re: os_process_error in CouchDB


I have upgraded couchdb to 1.0.2 and it still seems to be very very
slow. Did I mention very slow? :confused: We have less than 100 nodes (in
chef) and about 50 cookbooks and 20 or so roles. Very little is
applied to the nodes at this time. If I click on Status in the webui,
it take 3-5 minutes or longer to return a status.

The server is a VM with 2 vCPU’s and 4 GB RAM. It is not starved for
virtual resources… I do notice 60% paging when attempting to
reindex with knife index rebuild. I also receive timeouts during the
index rebuild with a message trying again. This eventually times out
completely and fails.

ERROR: Timeout connecting to for

The chef server and knife client are on the same host.

It is unusable in its current state.

Any ideas?

However, I could not find a couchdb 1.0.x from a trusted source for
CentOS 5.x. We have built a new server (CentOS 6 and couchdb 1.0.2)
but do not have time to migrate right now. If anyone knows where I
can find couchdb 1.0.x for CentOS 5.x that is from a reputable source, I
am all for it.

A few weeks ago, I cloned the server (VM) and downloaded a couchdb rpm
and tested that I could in fact just upgrade couchdb and it worked. But
again, I need a reputable source.

There’s a rpm available for 1.0.1, I don’t think it’s in centos or epel.
You should be able to get it via rpmfind. I agree with ian, you should

Is it possible to upgrade to 1.0.1 or greater? What OS you running?
CouchDB 1.0.1 is included in Ubuntu 11.10.

Hi Adam,

couch.log is 125000 lines long, so I’ll include the beginning
( and the end (
I’ll post to CouchDB’s mailing list too.

I have to add to my below description that after I rebuilt the
chef-server, I reloaded all of our cookbooks, roles and databags.

I do believe that Randy has the same issue, although I’m not sure what

version of CouchDB he is using.

Can you show us the full stack trace from CouchDB?

Have you showed it to the folks on the CouchDB list?

We are seeing a strange error in CouchDB that causes Chef to become
unusable and unrecoverable. The knife command ceases to respond, and

This is the second time this has happened. The first time, it

to our chef-server that was running properly for several weeks. On
Monday, at about 11 AM EST, the error occurred and our chef-server
became urecoverable.
We tried to research and recover the issue for about a day.

We then rebuilt the chef-server this morning. During the
setup/installation, we encountered this issue
which we had encountered in the past. We then applied the fix, by
increasing maxFieldLength in the mainIndex section of the chef solr
config file.

Very shortly after that, while do a chef run on a lab node, running a

knife command and trying to access the web UI all at the same time,
the os_process_error occurred again and the chef-server became

Our chef-server is running on a vSphere VM with 2 cores (2 cores in 1

socket), 2GB of RAM. It’s running Ubuntu 10.04 LTS, Chef 0.10.8 and
CouchDB 0.10. The VM was generated from a pre-existing VM that
originally had only 1 core.

Another detail about our environment that may be important is that we

use Centrify on our Linux server for Active Directory integration.
This is why we were affected by CHEF-2346. Since chef pulls in all
authorized users on a node as an automatic attribute, there can be
thousands of users in a list that gets gathered by chef.

Is perhaps CouchDB dying because of the size of the node data that we

are asking chef to gather? Has anyone else encountered this error?
Much thanks for any help. Let me know if I can provide any more
