Subject Re: problems with tomcat4 and jrun2.3
Date Tue, 10 Sep 2002 13:44:10 GMT
does the 100% utilization when either jrun or tc run by themselves?

try upgrading tc to 4.0.4 to see if there's a difference.  may want to also 
try tc4.1.10.

what version of jdk131 are you using?  131_04?  if not, try that also.

for problems like this, first try to isolate the problem (i.e. test the 
technologies individually, if possible), and second, upgrade to the latest 
(micro) version of supporting technologies (i.e. jdk131_01 -> jdk131_04).

if that doesn't solve the problem, try using a profiler to find out which 
class/method is causing the problem.
