[opencms-dev] MySQLNonTransientConnectionException - too many connections

Hi Kai,

There are no such jobs. The server's sole purpose is to run 3 OpenCms instances with MySQL, Tomcat and Apache.

I am convinced that the problem is related to traffic (or rather, the number of cuncurrent connections), and we have significantly more traffic during working hours (~9am to 5pm) than any other time of day. If I was to speculate, I'd say that a connection limit is reached. After this, any new requests are then placed in queue, and eventually the queue is also maxed out.

*Are my Apache and Tomcat settings good?*

When trying to restart everything, I also discovered an issue with disk space, caused by a couple of HUGE Tomcat logs (catalina.out and today's log were both >25GB). These logs maxed out the available disk space, causing all sorts of ill. For one, MySQL was unable to start... However, the disk space is not the root cause.

I discovered a probable cause for the huge logs just now. I had "tail -f catalina.out" open in a terminal window. Suddenly it exploded, writing this exception continuously (and at a _very_ fast rate, probably 10s or 100s of times pr. second!):
May 4, 2011 11:44:08 AM org.apache.jk.common.ChannelSocket acceptConnections
WARNING: Exception executing accept
java.net.SocketException: Too many open files
        [...]

Strangely enough, I did not notice the site becoming unresponsive while Tomcat was racing along with this exception.

Even before Tomcat went crazy, there were quite a lot of "Broken pipe" exceptions in Tomcat's localhost log (and the same for 404 pages):
May 4, 2011 9:28:07 AM org.apache.catalina.core.StandardHostValve status
WARNING: Exception Processing ErrorPage[errorCode=500, location=/opencms-errorhandler/system/handler/handle500.html]
ClientAbortException:  java.net.SocketException: Broken pipe
        [...]
Caused by: java.net.SocketException: Broken pipe
        [...]

Since this morning's restart of MySQL, Apache and Tomcat, there were no "Broken pipe" exceptions for a while. There was (and is still) nothing in MySQL's slow queries log. The site was responsive things seemed "OK", until Tomcats exception extravaganza.

Apache's error log complains a bit, though:
[Wed May 04 11:06:58 2011] [error] ajp_read_header: ajp_ilink_receive failed
[Wed May 04 11:06:58 2011] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (localhost)
[Wed May 04 11:06:58 2011] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header

These appear in bulks, with the above error occuring several times pr. second in each bulk.

Any more clues?

Best regards,
Paul
