Yes, there is an application using RMI. It is a SessionManager, which
communicates with a servlet.
But actually the application is located in same machine as JRun.
The original plan was to use it on the seperated systems with RMI.
I've got surprised...how do you know?
Any comment will help me.
Thanks for your kindness,

Hey Sean,
Are you using RMI also?

Hi!!
It may be that the customer starts the Jrun from a shell and when he closes
the shell , JRUN goes down. Start the Jrun with nohup command,
nohup ./jsmctl start
That should solve..

Subject: JRun 2.3.3 dies aperiodically once or twice a day
Hi,
Our customer has a problem using JRun 2.3.3 on AIX . Details are below ;
Machine: RS6000H70(4CPU)
OS: AIX 4.3.3
JRun 2.3.3 build 157 Unlimited
JDK: J2RE 1.2.2 IBM Build ca122-20000607b
Web Server: Netscape Enterprise Server 3.6
DB Server: Infomix RDBMS
The problem is that JRun is dying once or twice a day.
At that time, java process shows alive but no requests are accepted,
and only the message displayed on the browser are below ;
JRUN Connector Proxy requests timed out
Please contact the system administrator for this web site
Next is web server's log ;
[09/Aug/2000:17:16:57] warning (20070): for host 211.107.127.41 trying to
POST
/servlet/nacf_vcs, jrNSAPI[1124] reports: 127.0.0.1:8081 timed out after
waiting 300 seconds for [1]
In this case JRun will not restart ,so we have to kill the process and
start.
In addistion, We can see CPU idle is almost 100% and the JRun log has
nothing particular.
The value we use is default value in JRun, Max thread is 1000 , Min thread
is 1 and active thread is 100.
We also set the jcp logging option. There are nothing particular, too. The
logs are below ;
jcp [9/07:00:15:16] 97659kb, 5+1=8 threads, 1 peak, 0/1 rq delayed, 0
dropped.
jcp [9/07:00:15:26] 97659kb, 5+3=9 threads, 3 peak, 0/5 rq delayed, 0
dropped.
jcp [9/07:00:15:46] 97659kb, 5+2=9 threads, 2 peak, 0/3 rq delayed, 0
dropped. ==> dying...
jcp [9/07:00:15:56] 97659kb, 5+3=8 threads, 3 peak, 0/5 rq delayed, 0
dropped. ==> kill and start
jcp [9/07:00:16:06] 97659kb, 5+2=8 threads, 2 peak, 0/2 rq delayed, 0
dropped.
jcp [9/07:00:16:16] 97659kb, 5+4=9 threads, 4 peak, 0/4 rq delayed, 0
dropped.
jcp [9/07:00:16:26] 97659kb, 5+3=10 threads, 3 peak, 0/6 rq delayed, 0
dropped.
jcp [9/07:00:16:36] 97659kb, 5+2=10 threads, 2 peak, 0/6 rq delayed, 0
dropped. ==> dying
jcp [9/07:00:16:46] 97659kb, 5+1=11 threads, 1 peak, 0/5 rq delayed, 0
dropped. ==> kill and start
jcp [9/07:00:16:56] 97659kb, 5+2=9 threads, 2 peak, 0/5 rq delayed, 0
dropped.
jcp [9/07:00:17:06] 97659kb, 5+2=9 threads, 2 peak, 0/5 rq delayed, 0
dropped.
At the busiest time, total thread number is not more than 60.
One more thing, our customer has another problem with JVM.
We might find out the solution in that, I think.
They set the JIT compiler disabled. It is because the JRun dies more often
than when it is set enabled.
The Heap size is set Min. 100MB ~ Max. 500MB.
So what do you think I should check out for this problem?
Any suggestion and possibility will save us.
Thanks in advance.
