Subject Re: Java program interferring with Tomcat
Date Mon, 19 Nov 2001 19:04:07 GMT
It happens to me, but in reverse order - I think it is related to the
JDK/JRE itself, not to Tomcat.
I use the same environment (win2k, jdk or jre 1.3.1).

When Tomcat runs, and I launch the install shield for any installation from
Sun (Java related of course),
the installation programs sits there and does nothing - yet it's still

Stopping Tomcat suddenly wakes up the install program and everything's
I have noticed this strange behaviour a couple of times already and really
wonder why this happen.
I thought it has something to do with Win2K and Install-Shield (something
like a registry key lookup that takes forever to complete), but it's
apparently not the case...

As this does not happen with other install-shield based program, I think
there's something wrong in the JRE....

Subject: Java program interferring with Tomcat

    I have a server running Tomcat 4.0 on Win2k with the Sun VM JRE 1.3.1.
At 11am each day I have a commandline Java program scheduled to run using
Window's scheduler.  When this program runs, Tomcat becomes unresponsive.
The process appears to still be running, but I need to restart it to get it
to continue serving pages.  There are no errors in any logs.  The only
shared resource between the two programs is SQL Server.  There are two
processes running, so both programs should be in seperate VMs.

Any ideas?
