ArcBatchJobs failing

This bug appears very similar to NAS-1918. When running any ArcBatchJob as part of TEST11A (http://kb-prod-udv-001.kb.dk/private/Twiki/bin/view/Netarkiv/It36Legalbatchjob) the job hangs on the gzipped arcfiles in the KB test archive. Only the current job hangs - the system itself remains responsive. Logging shows that many arcrecords in the gzipped files are processed successfully before the job becomes unresponsive. The batch job runs to completion on SB without any problem. The java version
on KB is 1.6.0_12-b04 and on SB 1.6.0_25-b06. This is odd because according to NAS-1918 it is only the later java version on SB which should be problematic.
