Are you using some IPC events?  If so, run the K2 Service in console mode.  See if you get a lot of repeating messages that say 'Object not set to an instance...'.   If you see those messages,  open _IPCAsync table in the K2Server database.  If all of the above things are true and you see rows in the table, call the help desk.

In addition to David’s suggestion around checking IPCs; do you happen to use any Roles that are marked as Dynamic within the Workspace > Management > Roles area?  I’ve heard of CPU spikes when a rule was created as dynamic, but at the process level it is marked as not-dynamic (e.g. the Dynamic checkbox is not checked) but the refresh interval is 0.  In this case setting the refresh to something larger than 0 (10, which equals 10 minutes) is the default) resolved the issue.  You can find this setting by opening K2 Workspace then navigating “Management” and then drilling down to the desired process(es) under Workflow Server.   Once you expand a specific process you will see a node for “Roles” clicking on this will present the role settings for this process.

Hi Bob,

It seems you are right, i was creating a Role (Which Contains 2 users) and assigned this role as destination the one of the Process Activities. Then the problem started. When i removed this Role and i assigned a single user, the deploy took its normal time and the CPU usage went to normal.

My problem now is to know how to create a parallel action ?? since as i was reading in previous posts and in documents on the black market specailly ("K2 [blackpearl] Roles and Advanced Destination Rules"), i have to create a Role and assign it as destination to the activity. Since this action is causing other problems so how can i implement my Parallel action??

Thanks a lot
