We have Metastorm 7.6 installed on Windows Server 2003as UAT environment. For past couple of days
the server CPU has spiked to 100% sometimes. Investigation shows that DLLHost.exe is eating up CPU around 40-50percent all the time. Further investigation lead to the fact that 'Metatsorm Process Engine' service is responsible for DLLHost.exe behaviour. If we stop the service, DLLHost.exe usage goes down to 15-20%. As soon as we start the service the DLLHost.exe shoots up to around 50% constantly even with no web client logged. This causes CPU to spike around 90% overall. If any web client client is logged, CPU goes to nearly 90 to 100% and the sevrer become unresponsive.
Can somebody give any idea or any direction to investigate.

Thanks in advance.

look and see if anything is happening in the system. This could be in the following tables:


You will need to know what the contents of these tables mean in some cases, but if there is any change in total numbers in any of these tables over a few seconds (do a SELECT COUNT(*) from table with (nowait) if using SQL Server) will tell you that is the table to look at.

It sounds like an issue where sub-optimal use of flags is occurring. A flag is being raised against many folders, and a check is being made so only a very few folders respond. If there are any flag actions set to respond to 'any folder' and a condition is in the 'only start action if' property, check it.

Post an example, and we will have a much better idea what the problem is. In about 90% of posts, the problem is one of communication. Examples bridge that gap.
