The DeploymentManager status cache code tries to refresh its
information about applications by calling
the Application mbean in its servant.  If the
websphere.ws390.servant.started notification
has not been received yet at the control region, then this may
cause exceptions in the control region:
BBOO0222I: ADMN0007I: The getAttribute method results in
exception

There may also be an FFDC log created which shows:

In another case, the TraceService MBean proxy code was also
noticed to have the same issue with InstanceNotFoundException.

Problem conclusion

The code has been modified to wait for
websphere.ws390.servant.started notification.

APAR PM38627 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.41 of WebSphere Application Server V6.1.
and Fix Pack 8.0.0.1 of WebSphere Application Server V8.0.

Sysroute APAR PM46035 will be used to deliver this fix in
WebSphere Application Server V7.0.

Please refer to URL:

for Fix Pack availability.
