ORA-03113 when trying to connect to database

I've currently a 7.1.3 client on SUN Solaris (5.10 Generic_118844-26 i86pc i386 i86pc) where I want to connect to the 9.2.0.6 database on a Win2003 Server hardware.

When i try to connect via SQL*Plus (Release 3.1.3.4.1), I get ORA-03113. Looking into the listener resp. alertfile on the server, I can see that the connectiorequest is recognized, but immediately answered by an ORA-0600, producing also trc-files.

listener: 25-MAI-2007 09:37:23 * (CONNECT_DATA=(SID=HTASQL)(CID=(PROGRAM=)(HOST=eklvpa)(USER=sat250))) * (ADDRESS=(PROTOCOL=tcp)(HOST=172.17.233.3)(PORT=32790)) * establish * HTASQL * 0

alert: ORA-00600: internal error code, arguments: [12333], [26], [0], [115], [], [], [], []

Activating traces on the client-side showed the following errors:
-<ERROR>- ntus2err: sd=8, op=1, resnt[0]=511, resnt[1]=2, resnt[2]=0

Can anybody help me in determining the problem ? Is there a systemtic incompatibility in connecting a 7.1.3 client to a 9.2 (or even higher) database ?
