EHP 7 upgrade - Got stuck at Pre-processing - urgent help required

Question

hi Everyone,
I am upgrading my current ECC 6 EHP 6 system to EHP7. I got stuck in the Pre-processing phase "imports included Add-on and Support Packages into the shadow tables and the new tables". there is no error but it is runnign for more than 15 hours now. i dont even see a latest log showing its progress. The logs got updated 14 hours ago and there is no update after that.
The shadow instance was down. Main instance is up and running and no Jobs running. I manually started the shadow instance and checked if that will help . but no use. so restarted the SUM tool. it gives a different problem now. I have listed out the current probelms below. please check and advise
1. SUM tool shows, "ABAP- Starting handshake" - SAPUP.Out erro message (ERROR in GUI communication: Error in network interface: NIEINVAL (0/53 written))
2.Shadow instance up and running but while trying to login from GUI,it says "rabax during SAPGUI logon". i can see all its WP in 'waiting' status at the OS level
3.in DB02, "oldest Open Transaction" shows Aug 15 2014 10:30 PM, which means this transaction is there at the DB level for more than 16 hrs now.
Please help trouleshoot and resolve this. useful inputs will be rewarded immediately
thanks,
Shiv

I have resolved the 1st issue, after killing the SAPup process at os level.
now, in the SUM tool, it gives the following info,
Type                    |Name                          |ProcessID|Description
=============================================================================
Operating system process|E:\usr\sap\<SID>\SUM\abap\exe\tp|5144     |
                        |"pf=E:\usr\sap\<SID>\SUM\abap\va|         |
                        |\SHDALLIMP.TPP"               |         |
                        |put <SID> "-Dmainimp_proc=2"    |         |
                        |"-Dparallel=2"                |         |
If additional processes are still running or background jobs are active, the
program *must* wait for them before it is able to continue.
Be careful with stopping any process. If a background job is scheduled but not
running, delete this job using transaction SM37.
01)  -  Exit program
02)  *  Check status again
03)  -  Processes do not exist, continue
04)  -  Wait for processes to finish
: Check status again
TP program is running at OS level. but as already said, no background job runnig in Main instance and the shadow instance was already down. shal i kill this TP process and try with option 03) ?
please advise
thanks,
