phase RUN_RSGEN during SP implementation takes a lot of time.

Hello All,

I'm patching  CRM EHP1 to EHP2 to SP14 by using SUM.

The phsae MAIN_SHDIMP/SUBMOD_SHD2_RUN/RUN_RSGEN is runing for more than 25 hour.

No error logs in st22 or sm21. Background jobs " RSGEN_GENER8_SHADOW and RSPARAGENER8M"  running.

In SUM directory logfile RSGEN.log is getting updated quite often with just one exactly the same line:
.

2 ETQ399 'SUBST_CHECK_BATCHJOB' for JOBNAME='RSGEN_GENER8_SHADOW' JOBCOUNT='17582500' returns 'R'.
2 ETQ399 'SUBST_CHECK_BATCHJOB' for JOBNAME='RSGEN_GENER8_SHADOW' JOBCOUNT='17582500' returns 'R'.
2 ETQ399 'SUBST_CHECK_BATCHJOB' for JOBNAME='RSGEN_GENER8_SHADOW' JOBCOUNT='17582500' returns

I had tried to stop and start SUM agian. I get this massage:

Stopping the SUM process is not possible.

Any help for this problem

Thanks
