JVM Crashed on its way to start

Indranil Adak_1 — Thu, 19 Jan 2006 02:09:12 GMT

Hello,

We have a JVM Application(B) that got crashed on its way to start. Note that, this is application is spawned within another JVM Application(A). The problem is not reproducible.

The application B failed to write anything in the application log file, which made us think that it never started at all. This is also evident from the timestamp in the hs_err file generated by Java Hotspot. It means that the application crashed while being started up.

Could it happen because of less physical memory? Because, we think that, we should see a differnt message when enough physical memory is not available for starting up a JVM. We do not normally see the JVM crashing.

Any help will be greatly appreciated.

The contents of the hs_err file is given below.

Unexpected Signal : 4 occurred at PC=0x73421D80
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.

Without a clear error messge, it is very difficult to troubleshoot. The error signal 4 means illegal instuction. Aprt from what you see, do you any error messages at the time of application startup failure?? Check dmesg/syslog.log. Also check cpu,disk,swap,memeory utlization at the time of this error.

Last but not least, are you up to date on java patches??

Hello,

What is your Java version and patch level of your server ? You can grab the latest version from,www.hp.com/go/java and install the prescribed patcheds as well.

Hello,

There were no error messsages apparently available in the syslog.

As this problem was discovered after a certain period of time, we do not have the system level statistics.

Yes, we have already checked the Java versions and recommended patches. We are running JRE 1.4.2_07 with all the recommended patches available.

Regards
Indranil

Hello,

How do you invoke JVM in A and B ? Are there any parameters with comman option "java -D " ?

-Arun

Re: JVM Crashed on its way to start

Indranil Adak_1 — Mon, 23 Jan 2006 01:36:51 GMT

Hello,

We do not use any Java specific parameter using -D. We use an application specific property though.

e.g. java -D=

Please let me know if anyone is interested in debugging the core file. I can send it to the responder's e-mail a/c.

Regards

Shalom,

General recommendations.

http://www.hp.com/go/java

Install all required and recommended patches and their dependencies, which you get from the patch database:
http://itrc.hp.com

You may be able to do strings core to show the readable characters in the core file and upload that file.

HP support can allow you to email up to 5 MB and if you need to post a bigger file, they will set up a temporary ftp site for you.

On this incident, this is what I gathered on the system situations....

There was a MCA problem reported by /var/adm/crash. I will appended part of the info.

-rwxr-xr-x 1 root root 1 Jan 17 17:49 bounds
drwxr-xr-x 2 root root 8192 Jan 17 17:52 crash.6

There is some hardware problems but what is not sure where it is about 30mins after the JVM crash ie JVM crash around 17:14. And bounds and system dump at 17:49-17-52...

In the INDEX file, it shows...comment savecrash crash dump INDEX file shows the top few lines as:....

....
Clearly a MCA error..(hardware).

Now the question that I had, is this possible? ie JVM dumps first and then half an hr later, the system crashed.

Are they related?
thanks

apologize.

Chew Chye Guan — Mon, 30 Jan 2006 21:53:39 GMT

ops. looks like I got the wrong date..
Indranil's problem occured on 29 Dec 17:14 where else the MCA problem occurs on 17 Jan 17:42. apologize...
