An instance of Oracle EM 10g Database Control is already running.

Question

Hello all, I've this problem when I reboot my system and try to start EM console (because it's not working after each reboot until I restarted it):
Oracle Enterprise Manager 10g Database Control Release 10.2.0.2.0
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
http://IC-Server:1158/em/console/aboutApplication
- An instance of Oracle Enterprise Manager 10g Database Control is already running.
but if I check the EM status, these are the results:
IC605 on IC-Server: emctl status dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.2.0.2.0
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
http://IC-Server:1158/em/console/aboutApplication
Oracle Enterprise Manager 10g is not running.
Logs are generated in directory /u01/app/oracle/product/10.2.0/IC-Server_IC605/sysman/log
IC605 on IC-Server:The only way to solve this that I found -at least for now- it's to stop the EM console, and then start it again.
And contents of file emdctl.trc are these:
IC605 on IC-Server: cat emdctl.trc

Could you give any clue about where I must search for the problem?
Thanks a lot.

But I still have the same trouble with EM Console startup... After rebooting my server, I got this error:

IC605 on IC-Server:I must to stop and then to start it "again" to be able to use the EM.
Have you any idea?
