Symptoms

IPC calls take 3 minutes to return to calling workflow
 

Diagnoses

When you are calling a sub process that creates a new folder in SharePoint using the K2 control. This executes in about two seconds however the sub-process takes approximately 3 minutes to return to the parent process.

This is a reproducible issue, is there a way to help speed up the time it takes for the IPC to be completed?




 

Resolution

In regards to this issue you will need to do the following:

Go to >>> Program Files x86 >>> K2 Blackpearl >>> HostServer >>> Bin

Then locate the file K2Server.setup, then search for the following:

IPCSettings ExpireOnDelete="false" IPCThreadInterval="60"

Set the IPCThreadInterval to '5, and save. After this you can do a K2 service restart, this should reduce the time of how it take for the IPC call to complete.
