Hello -
We recently purchased four ColdFusion 10 Enterprise Licenses to refresh our production webservers. We are currently testing our buildout, and one of the two initial servers has been giving us intermittent issues. It seems that occasionally apache hands off the request to the coldfusion back end, but it never receives a response from the CF service, and the connection just hangs in a "W" Sending Reply state, with no obvious timeout. I do not see any active threads in the coldfusion Server Monitor. I see connections on the Apache server-status page that have been in the same state for 54,000 seconds and counting. The end result is that the browser just hangs waiting for a response, but never timing out. We estimate between 1% and 2% of all requests wind up in this hung state.
We have ensured that the /etc/hosts and /etc/resolve.conf files are correct. I see no obvious errors in with the apache logs or coldfusion logs.
Details:
Coldfusion 10 Enterprise
Apache 2.2.15
RedHat Enterprise Linux 6.5 - 64 bit
MySQL 5.6.19
Roughly 200 virtual hosts, each with a duplicate JkMountFile "/opt/coldfusion10/config/wsconfig/1/uriworkermap.properties"
Any help troubleshooting this installation would be greatly appreciated.
