Hello,
I'm running Tomcat 5.0.18 on RedHat 9, started with the following
commandline:
/usr/java/j2sdk1.4.2_01//bin/java -Xmx256m -server
-Djava.endorsed.dirs=/usr/java/jakarta-tomcat/common/endorsed -classpath
/usr/java/j2sdk1.4.2_01//lib/tools.jar:/usr/java/jakarta-tomcat/bin/bootstrap.jar:/usr/java/jakarta-tomcat/bin/commons-logging-api.jar
-Dcatalina.base=/usr/java/jakarta-tomcat
-Dcatalina.home=/usr/java/jakarta-tomcat
-Djava.io.tmpdir=/usr/java/jakarta-tomcat/temp
org.apache.catalina.startup.Bootstrap start
and with development=false and fork=true in the jsp servlet configuration.
This installation is serving around 200000 hits per day, much of it is
DB intensive. Before i set development=false and fork=true I had big
hangups when I changed the JSPs and Tomcat started recompiling them -
the whole engine practically stopped for a few minutes and the load went
up to 16 on the server. Now development and fork variables are set
correctly for deployment, but I am still having a strange problem.
Every now and then (probably every few hours, I can't tell exactly)
Tomcat stops for around 20 seconds. I noticed it when browsing one of
my sites, everything was working fast, and then at a certain point,
after I clicked on a link, the browser started connecting to the server
and waited for the response for a long time. When I checked the load on
the box it was 1-2 (normally it's 0.5), but didn't notice any processes
hogging the CPU with 'top'. I already fixed all DB connection leaks I
had so that can't be the issue here. Traffic peaks can't be it either,
I have constant traffic.
I know that this isn't a precise description of the error I'm
encountering but I don't have any more information at this point. I'm
hoping that someone encountered this already and can help me, or perhaps
you can give me directions how to figure out what's wrong.
Best regards,
W. Sobczuk
