I would suggest the following
1) deactivate wasp
2) use raw config to set loglevel to 3 and logsize to 35000
3) clear the current wasp.log and portal.log
4) rename the wasp\work folder to wasp\work_old
5) rename the wasp\webapps\root to wasp\webapps\root_old
6) activate wasp.
7) when you have a port and pid try to login
8) if you get the same error check the portal.log and wasp.log and open a case with support.
