After upgrading to the 10.2.0.5.0 release the database is encounter a file handle leak. The leak is seen in production and development instances. The leak happens on different processes (emagent and MMNL process are the current ones).
Test on growing of openfiles:
lsof -p 10140 |wc -l => 600lsof -p 10140 |wc -l => 759
Now we wait for the sollution of oracle to solve this bug.
The max file limit has been reached so the db will have to be shutdown or the
process killed, if possible, to free up files.The leak happen over time and manifests itself when the limits are reached as error ORA-27041.
