hi, friends:

    I have a rac running linux as2.1/kernel 2.4.9-e25/oracle 9.2.0.3(with some intermit patches). The server switched from old rac server/storage to current server/storage on July 16.

    But on July 24, there is some new oracm process running, too many oracm process than I have ever seen.

    I checked cm.log, there is no special log during July 24, all of them look like:(>WARNING: ReadCommPort: socket closed by peer on recv()., tid = 11305018 file = unixinc.c, line = 754 {Thu Jul 24 02:50:19 2003 }^). I noticed that all new oracm process is started by pid:1249(the first oracm process).

    My question is:

1. Have anyone noticed similiar too many oracm problem before?
2. Under what situation will the new oracm process be started?
