The first thing I would check is the virtual memory limit (ulimit -v, check
this for the operating system user that runs Tomcat /Solr).
It should be set to "unlimited", but this is as far as i remember not the
default settings on SLES 11.
Since 3.1, Solr maps the index files to virtual memory. So if the size of your
index files are larger than the allowed virtual memory, it may fail.
Regards,
André

Betreff: solr multicore problem on SLES 11
Hello,
I have a problem with solr and multicores on SLES 11 SP 2.
I have 3 cores, each with more than 20 segments.
When I try to start the tomcat6, it can not start the CoreContainer.
Caused by: java.lang.OutOfMemoryError: Map failed
at sun.nio.ch.FileChannelImpl.map0(Native Method)
I read a lot about this problem, but I do not find the solution.
The strange problem is now:
It works fine under openSuSE 12.x, tomcat6, openjdk.
But the virtual maschine with SLES 11 SP 2, tomcat6, openjdk .... it
crashes.
Both tomcat/java configurations are the same.
Has anyboday a idea, how to solve this problem?
I have another SLES maschine with 5 core, but each has only 1 segment
(very small index), and this maschine runs fine.
Greetings
Jochen
