Hi Daniel,
Valgrind is probably the most common method of tracking memory problems on Linux I am aware of. Please note the following document on monitoring Virtuoso memory consumption: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtMonitorMemoryConsumption Also, note the following 2 parameters: ThreadCleanupInterval, ResourcesCleanupInterval which can both be set to 1 in order to reduce memory leaking: http://docs.openlinksw.com/virtuoso/databaseadmsrv.html#ex_threadcleanupinterval although as this was not apparently occurring with 7.2.0 it may not help, but worth trying ... How is this "process to convert MeSH XML to MeSH RDF" which uses lots of memory performed, is this done in Virtuoso or by some external process ?
