When trying to connect AS SYSDBA with Sqlplus on a Unix style system an ORA-12547 "TNS:lost contact" is signalled and a trace file is generated which contains an internal error as follows:

----- Error Stack Dump -----
ORA-00600: internal error code, arguments: [spstp: ORACLE_HOME uid does not match euid], [xxxx], [yyyy], [], [], [], [], [], [], [], [], []
----- SQL Statement (None) -----
Current SQL information unavailable - no SGA.

Where xxxx (uid) is not equal to yyyy (euid), the call stack module is : spstp() .


The permission (chmod) settings on the oracle executable were changed.
