Following is the stack trace. I read that the Broken Pipe is because of Unclosed connection for 8 hours and the connection close automatically. I saw this http://itellity.wordpress.com/2011/05/18/getting-rid-of-socketexception-broken-pipe-with-quartz-and-mysql-on-jboss/ .I could not reproduce in my local machine.

Is there any way I can reproduce this in my local machine.
Will this make a tomact crash? I am using a very old version of quartz jar 1.6.5 and tomcat 6.0.18. will that be an issue.

Please help me to resolve this issue.

EDIT:
I am using

org.quartz.dataSource.QUARTZ_NO_TX.validateOnCheckout = true
org.quartz.dataSource.QUARTZ_NO_TX.validationQuery = select 1

on my quartz properties also

autoreconnect=true

Is there any way I can reproduce this by changing the mysql properties. I am getting this only on my server.

I believe it is related to MySQL stale connection that is dropped after 8 hours.

EDIT

Read this article.

Make sure you have the following set (not sure about the exact attributes’ names but they should be similar to the mentioned below)

testWhileIdle=true
validationQuery=”SELECT 1″
minEvictableIdleTimeMillis=1800000
timeBetweenEvictionRunsMillis=1800000
numTestsPerEvictionRun=3
