G'day!
I beg to differ. The relevant bit is the first line, the filesystem /u100/app is full. Arvind informs us that the dump directories bdump, cdump and udump reside in that filesystem. If the ksupc2() function needs to write to this filesystem when spawning a new user process, e.g. to a trace file in /u100/app/.../udump, then it will fail and it may well log an error. One would have hoped it would be more useful than the ORA-600 that is being discussed though.
Perhaps this is related, but only one of several issues that conspire to raise ORA-600 rather than a "file does not exist" or similar message.. Does the ORACLE_HOME happen to reside in the same filesystem? In that case it could be memory related as Oracle writes to several files in $ORACLE_HOME/dbs, amongst others. 

Cheers,
Tony

    Thanks for your suggestions


    I found the following in /var/adm/messages.  /u100/app is the
    location where all bdump/udump/cdump resides and it was full that
    time, should it be the reason for

    ORA-00600: internal error code, arguments: [ksuapc2], [48956]
