In addition, many bugs were fixed, see the list below.

ARC Compute Element

An issue were A-Rex occasionally crashed due to logrotate is now fixed.

API changes

API changes from libraries version 4.1.0 to 4.2.0 are documented at NorduGrid Wiki.

Known issues

• There is a memory leak when using Java API for multiple job submission with files to BES interface.
• The CPU time is not measured correctly for jobs that kill the parent process, such as some agent-based/pilot (e.g., ALICE)
• JURA will not publish records to the APEL on a standard Debian/Ubuntu system, because the python-dirq package is not available for them. The workaround is to build this package from source.
• arcmigrate is currently non-functional
• Jobs submitted through EMI ES cannot be renewed
• When using ARC client tools to submit jobs to CREAM, only JSDL can be used to describe jobs, and the broker type must be set to Null in the client.conf file
• ARC GUI (arcjobtool) is not available yet, pending implementation of client library changes.
• Standalone client tar-balls for Linux are not yet available.
• Bug 2905 is solved using workaround. Source of problem is not yet identified.
