Subject Re: ajp13 dies unexpectately
Date Mon, 16 Jul 2001 20:41:04 GMT
How many threads have you specified as max_threads in your PoolTCPConnector
for ajp13 in your server.xml file? If you haven't done this, and you're
running a reasonably high load, you should take a look at the minimal TC
user's guide here:

The last example at the bottom of the page shows how to configure
max_threads, max_spare_threads, and min_spare_threads for the
PoolTCPConnector class. Tomcat doesn't react gracefully if the max_threads
number is ever reached and exceeded. I believe the default max is 50
threads. If you're getting more than 50 concurrent connections, you need to
raise this number or you'll have problems.
