Subject Re: APR SSL error: "Socket bind failed: [98] Address already in use"
Date Sun, 20 Nov 2011 21:59:27 GMT
Changing from jdk1.7.0_01 to 1.6.0_20 still results in the same error.

I use the following commands to stop and start Tomcat:
sudo /etc/init.d/tomcat6 stop
sudo /etc/init.d/tomcat6 start

I have verified that the Tomcat process DOES shut down when initiating
a "stop" command via "ps -ef | grep java" only showing the current
"grep" command.

Ubuntu's "apt-get" put me at this current level (of Tomcat 6.0.24 and
APR from 1.1.19-1) which I assumed would be fine.  I'll see about
trying to upgrade to Tomcat 6.0.33 and possibly APR 1.1.20-1.

Any other ideas would still be appreciated.

Thanks
