[jboss-user] [JNDI/Naming/Network] - Ports disappear in JBoss 3.2.6

[Sekhara]

Please Help !!!
Hi,

We are running a CRM application on JBoss 3.2.6. across 4 HP Unix hosts. Each unix host possesses 4 JBoss Process Kernels.
The lsof utility provides a breakdown of each pid. This is what i see which is quite wierd. If anyone can give me an explanation i would be most greatful !!!

-----------------
The pids listed are those belonging to each VM on one host and was taken on 070622 at 17h16.
 
$ grep LIST instfd_mp2hs100_070622_1716.log|grep 280|grep -v 4099
java    11434 user 68u  IPv4  0x958e2280       0t0     TCP *:9280 (LISTEN)
java    11443 user 68u  IPv4  0x5f0d2500       0t0     TCP *:10280 (LISTEN)
java    11453 user 68u  IPv4  0x60271880       0t0     TCP *:11280 LISTEN)
java    11462 user 68u  IPv4  0x5f0d2500       0t0     TCP *:10280 (LISTEN)

About 12 minutes later, the pids are all the same, implying that the VM's were not restarted, but the listening ports are now all 9280 on the same host ????? Why ?
$ grep LIST instfd_mp2hs100_070622_1728.log|grep 280|grep -v 4099
java    11434 user 68u  IPv4  0x958e2280      0t0     TCP *:9280 (LISTEN)
java    11443 user 68u  IPv4  0x958e2280      0t0     TCP *:9280 (LISTEN)
java    11453 user 68u  IPv4  0x958e2280      0t0     TCP *:9280 (LISTEN)
java    11462 user 68u  IPv4  0x958e2280      0t0     TCP *:9280 (LISTEN)

Any ideas ?
Regards
Chan
