JVM crashes with Sun JVM 1.5.0_6

kevinr — Thu, 26 Jan 2006 08:50:21 GMT

If you are running Sun JVM 1.5.0_6 (Windows or Linux) you may see the Alfresco server crash with the following report:## An unexpected error has been detected by HotSpot Virtual Machine:## SIGSEGV (0xb) at pc=0x40520cd1, pid=31769, tid=2309221296 # # Java VM: Java HotSpot(TM) Server VM (1.5.0_06-b0

It is not capturing the file. I don't know how to resolve the issue, it is the stock windows download off the web site so its very wierd it is not picking it up properly. The Sun link was also dead.

Hi

Which OS/JVM are you using?
Where are you putting the file?

It all works for me with 1.5.0_06 on windows.
I am sure we have also tested this fix for linux.

Regards

Andy

Hi Kevin,

I'm using the 1.5_06-b05( newest) and the Alfresco JBOSS distribution and I see that the .hotspot_compiler file is already in alfresco/jboss/bin and I'm getting the crash. The link for the sun bug report is also dead.

Cheers,

Hi,

FYI with the latest bundles we are using:
-XX:CompileCommand=exclude,org/apache/lucene/index/IndexReader$1,doBody
JAVA_OPTS argument instead of the .hotspot_compiler file to eliminate these issues.

Thanks,

Kevin

Hi Community,

I suppose people around here have been trying other JVMs than the bundled version 1.5.0_06?

I experienced crashes with CIFS/FTP uploads as well as with a modified version of the Webservices Import sample code with the above JVM. With JDK 1.5.0_08 as a replacement of the bundled JVM I haven't been able to reproduce the problem. Looking good so far, but still testing.

Regards,
Oliver.

We found a couple of further issues with the 1.5.0_06 JVM - it definitely has a few bugs! The following was required in .hotspot_compiler file to eliminate all HotSpot issues:

exclude org/apache/lucene/index/IndexReader$1 doBody
exclude org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger mergeIndexes
exclude org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger mergeDeletions

Hopefully the 1.5.0_08 fixes those problems!

Thanks for letting us know,

Kevin

I seem to have the same problem, but the strange thing is I'm using JVM1.5.0_05-b05

In My log I get:

So is reverting to this version really a solution?

I said 1.5.0_08 not 1.5.0_05. And yes I can confirm that the 3 hotspot bugs are indeed fixed in 1.5.0_08.

Thanks,

Kevin

Yes, that's what you said in your post of sep 6, but in the first post of this issue (jan 26) you said:

You can either:
1. Revert to Sun JVM 1.5.0_5 (which does not appear to have the problem)
2. Remove the method from JIT compliation

…and since I'm currently using JVM 1.5.0_5 I wonder why I seem to have the same problem…?

Thanks,

Hi,
I tried this an had the same error with 1.5.0_09 on a fresh CentOS 4.4 install yesterday. There were also filesystem problems (old scsi drives) which have since completely hosed the entire installation, but I definitely got this with CentOS 4.4, sun java 1.5.0_09 and the trial enterprise jboss 1.3.1 - all downloaded and installed yesterday…
Cheers
Antoine

Antione,

What i've found is that for highly loaded environments its a combination of java, and Redhat's thread safe libraries (tls) that seem to be causing the crash. What we've done is disable tls. It forces java to spawn new processes to handle requests, but avoids the complexity of individual threads in a single process. Which is also known to cause problems with Xen server virtualization. We can now do file operations (like copy 5 GB across machines with no issues).

This does in theory slow down the system a bit, but in our estimation is worth it for the increased stability.

It also may be possible to use a fixed version of tls (see the Xen mailinglist for information about that), but so far all we've done is disable tls.

mv /lib/tls /lib/tls.disabled
mv /usr/lib/tls /usr/lib/tls.disabled

reboot
