spum4 scan - memory issue/lack of parallelism

Hello all,

In the SPUM4 reprocess scan, we are unable to run more than 1 scan on big tables, encountered several memory issue (TSV_TNEW_OCCURS_NO_ROLL_MEMORY, TSV_TNEW_PAGE_ALLOC_FAILED, SYSTEM_NO_ROLL). Data is production copy, assigned at least 90% of the vocabulary by importing from previous upgrade of the same prodcopy.

We are using dedicated 8-CPU, 64bit W2003 server, 77Gb page file, with high value of 'memory related parameters (below)
