I am trying to load a large ontology (>6 million lines of OWL) into SHER using the $SHER_HOME/bin/LoadForSHER.sh script.
I am using Gentoo, but believe I have pinned down all the dependencies. db2-express-c is installed and seems to be working. The test data successfully imports (from the dump) and the test queries sucessfully execute.
I assume my configuration files are correct since the script executes for some time before failing. Here is the command I am issuing:
./LoadForSHER.sh rps ~/work/rps/tools/processing/rps-sher-config.cfg ~/work/rps/tools/processing/rps-sher-filelist.txt
Initially this produced a Java OutOfMemory error, so I edited the script so java is called with the -Xmx2024M switch. This allowed the script to run for some time (10-20 minutes on 3.6 ghz quad-core machine) before failing (presumably) with the following outout:
/home/silas/work/rps/tools/reasoners/pellet-1.4
Creating new rps
Selecting rps
/home/silas/work/rps/output-exclude/ontology.owl
./LoadForSHER.sh: line 15: 11460 Killed java -Xmx2024M com.ibm.research.sher.utils.LoadForSHER "$@"
It is not clear to me what 11460 refers to (is it a process?). Any help in diagnosing this problem much appreciated.
