JVM crash? No Ping Received - Stopping server

[Vishal Biyani]

The websphere server gets restarted saying " No Ping Received - Stopping server" and at the same time following is logged into sys outs:

The ping timeout value for Websphere was changed from default 200 to 400 and then 2400 but that didnt help!

#
# Java version:
# HotSpot VM (1.0.1fcs, mixed mode, PA2.0 build 1.2.2.14-02/11/20-PA_RISC2.0)
#
# HotSpot Virtual Machine Error, Unexpected Signal 10
#
# occurred at pc=0
# Error happened during: mark sweep
#
# Error ID: /CLO/Components/JAVA_HOTSPOT/Src/build/hp-ux/../../src/os/hp-ux/vm/os_hp-ux.cpp, 3075
#


Any idea??

The server is running on HP-UX box and the problem seems not to be with the Websphere application server, as we have seen from logs, the crash happens at time of GC only

Hello,

If its a problem with GC, you can try updating JVM to latest version whichever is available.

from your error log:
"Unexpected Signal 10 " => bus error occured,
"occurred at pc=0" => seems trying to execute some code at @0

=> check installation of JVM and websphere (swverify)
=> update those to latest release.

Shalom Vishal,

JVM does not usually crash networking.

ping is not available to non root users on HP-UX.

So I'm wondering what this message really means. Perhaps Java has its own version/kind of ping. If so it could be a networking issue.

As I have observed just now, when it says "No Ping Received" it does not log the JVM error. And when it does not show "Ping" it will log the JVM error (unexpected signal 10 and sometimes 11). Can it be related to some OS level patches? As system has been upgraded recently, and if yes what way to identify it?

Hi,

check if your system meets java patches requirements:

consider checking your system with hpjconfig to verify your system:
