Betreff: [chef] chef-server stops responding ever other request

Hi List,

maybe you can help me wit this? I've set up a "chef playground" with a 
workstation, a server (+UI) and two clients. While everything works so far 
the 
chef-server is making huge problems. I currently have to restart it after 
every REST-call because it won't react to anything afterwards (until 
restarted)

Example: I add a client (success) afterwards I try to add a cookbook (no 
response). Even a simple client connect is enough to stop it

according to ps and netstat the merb process is still running and listening 
to 
port 4000. And I can telnet to the port.

chef-server just hangs and is not responding to anything. Not even the gui. 
After restart it's working again for one request.

chef-server is started like this:

    /usr/local/bin/chef-server -d -e ${ENVIRONMENT}

where ENVIRONMENT is "production"

The "server.rb" is as follows
---------------- server.rb -------------------
log_level          :debug
log_location       "/var/log/chef/chef_server.log"
ssl_verify_mode    :verify_none
