i had seen service is registered with specific account, so i thought that user logged off from the machine that may be the reason behind it or any LAN disconnection problem . But Having taken another look at the above entry we seem to have a constant failure being generated in vmd which causes Trunk to detect vmd requires a restart. Most of the time it works OK and the restart count is anything up to 4. In this case the Trunk log confirms that the Restart Count is 5 and so is considered to be exceeded. Presumably, this triggers the termination of the other services and Trunk is actually doing its job.So, coould this just be a timing issue and we need to increase the tolerance level (i.e restart count) or do we need to address the 0xa08990002 error in vmd?
