Tomcat keeps to hang up

Check you tomcat logs. Sounds like a crashed JVM or an OutOfMemoryException (probably due to some customer's bad code).

If' I've said it once, I'll say it a thousand times, if you don't know how to troubleshoot Tomcat issues, do yourself a favor and not offer it as a service until you've spent PLENTY of time learning how Tomcat operates. If you don't, you'll give yourself nothing but headaches and lost sleep (not too mention plenty of pissed off customers). Tomcat requires far more knowledge than things like PHP and Perl when it comes to general maintenance and troubleshooting.

 

Sometimes you have the weigh the pros and the cons. Does providing it to keep the customers requiring it with you really cover the "cost" of the hassles you'll deal with until you are comfortable enough to manage it. Never be afraid to lose a few customers because you just can't support a certain technology; focus on what you are good at and then add new technologies once you are comfortable with them (your customers will be much happier in the long run).

We've turned plenty of customers away requiring things like Zope/Plone, Ruby, EXO, etc. because the time and energy needed to provide proper support just doesn't justify what we would make from the select few that ask for it. A quick cost-benefit analysis is always a good idea; never bite off more than you can chew, and never try to be the "end-all-be-all". Words to live by.

 

Well said!
