Jazz Foundation RDF index corruption on Linux 64-bit when using IBM JRE 5

Jazz Foundation RDF indexes can be corrupted on Linux 64-bit when the Jazz Server in mapped/io mode, is running with an IBM JRE 5.

Components related to the issue include:

• Operating System is Linux 64-bit
• The Jazz Server is running with an IBM JRE 5,
• The Jazz Server is running in mapped/io mode,
• The server log is filled with CRJZS5213E

The problem occurs when the indexes reach a certain size - between 14 and 16 GB - and some files reach 2Gb.

Note: Jazz Based product can be either Rational Team Concert, Rational Requirements Composer or Rational Quality Manager. Some RDF statements are missing in the RDF indexes and the .log file is full of entries like the following one:

2010-12-16 22:31:16,627 [  jts.jfs.triple.indexing] ERROR com.ibm.team.jfs - CRJZS5213E Unable to store index to RDF index:

This issue is caused by a problem in the Linux 64 IBM JRE 5 (pxa64devifx-20100511a).

An exception occurs when the size of a FileChannel reaches 2 GB:

java.io.IOException: Invalid argument
at sun.nio.ch.FileChannelImpl.truncate0(Native Method)
at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:769)

Operating System is Linux 64-bit

To resolve this problem, run the Jazz Server with a supported 1.6 JRE.
