Hi all
My alfresco-1.3.0-linux mostly works as expected, but sometimes I get an error in catalina.out like the message below. Restarting alfresco then seems to make everything work again.
My environment is a linux-vserver with arch i386 running on a fc4-x86_64 box. The linux-vserver has default (i.e. minimal) privileges.
Any ideas? Should I really try to submit a bug with sun microsystems?
…I found that the errors always happen during lucene indexing, in the hs_err.pidxxxx file I find:
Current CompileTask:
opto:2142 org.apache.lucene.index.IndexReader$1.doBody()Ljava/lang/Object; (99 bytes)
Is there a simple way to prevent lucene from indexing large documents? We don't need these indexes in these cases anyway.
Regards
–Marcel

This is an known issue with the JDK 1.5_06 JVM - if you upgrade to JDK _08 or _09 it is fixed.
Or if you can't upgrade, you can create a file called:
.hotspot_compiler
containing the following lines:
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
and place it in the bin directory of tomcat.
Thanks,
Kevin

Hi,
For your information, the bug persists.
Under debian linux, with jvm _09 :

That's a shame 
we have not yet seen it return using _08 or _09 JVM. I guess you still need the hotspot compiler setting until Sun fix this

ok, just a question : does this quick fix downgrades any alfresco feature ?

Hi
The hotspot exclude just stops the hotspot compiler from trying to optimise (and in this case badly) the specific methods. So there is no functional improvement.
It would help us if you could look at the hs_err_pid2428.log file, which should say exactly which method caused the problem.
Cheers
Paul.

Hi
Indicates a problem in the JVM garbage collection.
There are other similar reports to be found on the web - see http://forum.java.sun.com/thread.jspa?threadID=764551 for example.
I would suggest trying a different version of the JVM and/or changing the garbage collection options.
Regards
Andy
