Closed as program error.
Error description
From the logs we can see that there are a couple of reboots happening in a short amount of time. After the first reboot the Agent started normally and began to re-process the files pre-cached by the multiple action group which the agent had received a couple of days earlier. This is normal and it is done to verify and reorganize the cache. During this processing, the agent received a new stop command due to the second reboot request. The stop arrived at a time when the agent was still dealing with the cache files and had its content in an inconsistent state. Having been interrupted in the middle of the process and being the cache in an inconsistent state, the agent, before exiting, started the recovery procedure that ended up in the infinite loop. Because the reboot had to complete, the agent process, hung in the loop, was killed. At restart, the agent tried again to clean up its cache ending again in the code that causes the infinite loop.
Local fix
In order to recover the client, it is necessary to execute the procedure below: 1. stop the IBM Endpoint Manager client process 2. delete the <Client Install Path>/__BESData/__Global/__Download folder from the IBM Endpoint Manager Client cache 3. restart the IBM Endpoint Manager client process Or upgrade to IBM Endpoint Manager clients to 9.1 version.
Problem summary
Under some specific conditions the IBM Endpoint Manager 9.0 client may enter an error loop. In such a situation, the client starts using all of the CPU's resourcess and becomes unresponsive. While performing the download of a file or checking the status of a pre-cached file, the IBM Endpoint Manager client creates some metadata files in its cache. If an external event triggers the IBM Endpoint Manager client stop procedure in the exact moment the client is in the process of writing the metadata files, the client may enter into a loop while attempting to clean up the partial data. At the next start-up the client will enter again into the same loop while it tries to recover from the same error condition.
Problem conclusion
Fixed in IBM Endpoint Manager 9.1 Clients
Temporary fix
