Hi,
       If you feel that can be outofmemory problem, then you can monitor it
by running JVM with -verbosegc mode. For that you can wirte this otion in
jrun properties file in front of 
                                           java.args = -ms32m -mx64m
-verbosegc

Rcommended maximum meomory for JVM is half of your whole system primary
memory.

It will give the all statistics of your memory allocation on $ prompt
itself. I don't for see any problem with JRUN for concurrent requests.

        Subject:        Re: too many concurrent requests

        Well, I'm getting this same error.  I'm using Solaris2.8,  Sun's
java1.2.2.05a and I have
        -Xms64m -Xmx128m as an additional argument for the jvm settings for
the jrun server.

        Has allaire confirmed that the Sun 1.2.2.05a is safe?

        My log files don't give any info at all....
        event log has: 07/30 23:32:28 info (license) Enabling unlimited
concurrency for Professional

        error.log has nothing ... no out of memory error

        This has happened when I'm the only one running it and I haven't
made hardly any requests?
        While I know it could be apps, the apps are the same that have been
running fine on Jrun
        2.3.3.
        I'm supposed to go live in one more week with Jrun3 and now this has
me scared.

        Anyone who has had this problem find anything that might help me?
I've noticed quite a few
        people
        posting about it.   Also, would be nice if the Knowledge Base talked
about what to do for
        Jrun 3 for this error.
        I read the 2.3.3 Faq, but didn't think those things applied.
