Dear upgrade-gurus
I'm upgrading a sandbox system from NW701 to NW73. But unfortunately the upgrade hangs in phase PREP_SPACECALC/EU_IMPSPC 
Ther is no logfile written in /usr/sap/SID/SUM/abap/log. TOP shows SAPup running like hell, but nothing happens! I restarted upgrade process and repeated the phase, but nothing changed.
ls -ltr on /usr/sap/SID/SUM/abap/log shows:
