SQL statement breaking the connection with ORA 3113

Hi,

I did up upgrade 7.3.2 --> 7.3.4 ---> 8.0.5 on UnixWare 7.1. Which is not certified.
However, I have this ProC program which does not work anymore, at one stage is doing
an "update ...set X = NULL ..." and it can not perform it. It actually breaks the connection
and returns ORA-03113. I have tried manually, I inserted a new row and left column X (it's VARCHAR2(2))
null, I can update any column but this one, regardless of the value. Tried NULL, ' ', 'Z', but no luck.
My sqlplus session gets disconnected after a while. Any idea ?

Thanks,
