i converted DBGs to INFOs in DSMFactory::preloadModules and
DSMChartReader::importModule and added some infos. that produced to
syslog:
Sep 17 16:01:14 lohi sems[14949]: [#7f39c1316740] [preloadModules, DSM.cpp:878]
INFO: preloading 'mod_py'...
Sep 17 16:01:14 lohi sems[14949]: [#7f39c1316740] [importModule,
DSMChartReader.cpp:257] INFO: loaded module 'mod_py' from
'/usr/lib/sems/dsm/mod_py.so'
Sep 17 16:01:14 lohi sems[14949]: [#7f39c1316740] [preloadModules, DSM.cpp:884]
INFO: checking last_loaded
Sep 17 16:01:14 lohi sems[14949]: [#7f39c1316740] [preloadModules, DSM.cpp:886]
INFO: checking last_loaded->preload
the only explanation that i can come up with is that
last_loaded->preload() never returns.
