ORA-06034:

NETDNT: connect failed, partner exited unexpectedly
Cause: Connection with host node was made but partner aborted
Action: Make sure object (see 06031, above) is working (for VMS run the command file and make sure that the ORACLE server process starts up); sometimes happens when the network/node is under stress - in this case a retry often works.
