Unlock tasks manually

Hi All,

We have been facing an issue under high load. Under high load, task rows seem to get locked and task updations fail with the following message:

[POP.017.0001] Task is locked and you may not update it at this time. Please wait till task is unlocked )

We are using webMethods 7.1.3

Now, while searching, I found that in 8.2 we have the following Optional setting:


I would like to know if the option can be used in webmethods 713.

I would also like to know what happens once the valid time has completed? If a task updation in progress, hen will there be loss of data?

Is there any other way to unlock tasks?
