Specs and variables:
Windows NT 4 SP 6
Tomcat v4.1.18
JDK v1.4.1_01
CATALINA_OPTS=-Xms128M -Xmx1024M
At random intervals I get this error on console, it seems
that the socket for port 80 is closed and the server stops responding
What steps can I take to get more information about why this error is
occuring?
