Agent blocked....

In our 11g Grid Control I noticed an agent that was not uploading any data to the oms anymore.
When checking the status of the agent I noticed the following:

Last successful upload : (none)
Last attempted upload : (none)
Total Megabytes of XML files uploaded so far : 0.00
Number of XML files pending upload : 199
Size of XML files pending upload(MB) : 50.03
Available disk space on upload filesystem : 28.80%
Collection Status : Disabled by Upload Manager
Last attempted heartbeat to OMS : 2010-08-06 11:11:46
Last successful heartbeat to OMS : unknown

So, it seems to be disabled by the upload manager ??? When forcing an upload using the '
./emctl upload agent' it showed the 'oms version not checked' error. Because this a very common error, I decided the focus on the 'disabled by upload manager' error.

It seemed the agent was blocked for some reason. To fix this problem I did the following :

1. In Grid Control 11g go to Setup->agents-> Misconfiguration Alerts and Blocked Agents

You will see the 'blocked' agent in this section.

2. Go the home page of the blocked agent and in the right upper corner press the button 'Resynchronize'
3. When succesful go back to the setup page in step 1.
4. Unblock the agent
5. force an upload on the command line..

./emctl upload agent

The agent is up and running again.

Check you file for the agent. The default for upload is 50Mb...

# The maximum number of megabytes(MB) the upload manager will support in the
# upload directory before temporarily disabling collections, logging and tracing
