Tomcat ServerSocket Dies

[Steve McIntyre <sm...@tickets.com>]

Hi,

We are running some heavy load testing using Tomcat 3.1, JDK 1.2.1.04 on
Solaris with Apache and Jserv. As our tests ramp up, we invariably get the
error below. We have changed our file descriptors from 64 to 256, but this
did not appear to change the results.

Per below, we are using PoolTcpConnector connector or 500 max connection,
and 200 & 100 max/min spare threads respectively.

Any ideas what the 'too many open files' really indicates?

Thanks for you help!
