Hi all,

Since yesterday I have seen that one our dbs been spurting out:

Process m001 started up but failed with error = 20

in the alert log. I have a feeling that this might have caused our nightly RMAN backup to fail with the following error:

[SIZE=1][SIZE=3]RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-00020: maximum number of processes (%s) exceeded

What does the alert log message mean? It happened at around 10pm which is when the backup starts to kick in. Any clues will be appreciated!
