SIGSEGV problems in HotSpot VM

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
