Detailed notes

The following issues were fixed in the ARC core:

An issue where the watchdog daemon died with segfault is most likely fixed.
An issue where submitting many jobs that required stage-in/stage-out caused A-Rex to segfault was fixed.
gridftp now uses delayed passive.
Several issues causing DTR crashes were fixed.
Additionally several minor issues were fixed, see list of fixed bugs below.

No changes

The following issues were fixed in the ARC Information System:

The following issues were fixed in the ARC Clients:

Work around blocking semantic when using old Sqlite bindings and increase lock timeout to 10 s also when using new bindings. (GGUS-115392)

No changes

Since ARC 15.03 update 3, the following bugs were (partially) fixed:

3470 Watchdog did not restart arched after segfault
3473 A-rex crashes after input/output jobs handling
3487 ACIX picks up cachedir in arc.conf from nordugridmap section
3498 Document how the sysadmin can manually add GLUE2 OSName, OSVersion, OSFamily
3501 The presence of acix_endpoint option in arc.conf changes the SURLs of the input files
3505 ACIX produces not only acix-cache.log, but also twistd.log
3507 DTR crashes, possibly from corrupt file in cache
3510 arcstat and arcsub uses unsafe temporary files
3511 seg fault in DTR during ACIX/Rucio resolving
3512 ARC doesn’t use delayed passive for gridftp
3513 submit-pbs-job incorrectly specify local job priority

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.
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.
JURA cannot send/store local user ids
A-REX can under some circumstances lose connection with CEinfo.pl and go into an infinite loop. The only current workaround is to restart the a-rex service.
