Hi, backups of EM are failing suddenly. It shows "Initialization failure" in status and error log shows "Step aborted because agent went down". The error comes after many hours, I see that it doesn't write nothing in the oputut dir of the backup. If I do "$ tail -f emagent.trc", it shows some warns and the errors: 2011-08-29 09:43:25 Thread-4136277696 ERROR TargetManager: TIMEOUT when compute dynamic properties for target ora10g.localhost.localdomain 2011-08-29 09:43:25 Thread-4136277696 ERROR TargetManager: target {ora10g.localhost.localdomain, oracle_database} is broken: cannot compute dynamic properties in time. 2011-08-29 09:43:25 Thread-4136277696 WARN collector: the column name DiskActivityavwait in this condition does not exist 2011-08-29 09:43:25 Thread-4119632784 ERROR upload: Error in uploadXMLFiles.
