Subject: Why do Threads stall unless mouse is moving
I have a user reporting that threads in my app are stalling unless
she constantly moves the mouse.
I remember seeing this discussed on the list in the past but I can
come up with the right search terms to find it in the archives.
Anyone remember what the cause or fix was, or how to find it in
the archives?
This was mentioned by Joe and other back in September. I also saw
this with 2006r4, but thought that we'd resolved it by uncovering a
pair of Timers that were attempting to update the same progressbar
resulting in a potential spinlock situation. However, I've just had
reported by two different users in the same morning that the stall
still occurs in the latest BETA build of one of our apps. The stall
does not occur when the app is run in the IDE or if built with 2006r2.
At first, we thought that it was related to threads, but this app
uses and more top-down process mode, so not threads are involved.
Basically, a long-process shell execution occurs (unloading a tape
from a drive in a library, returning it to its slot, and then loading
the next tape. The procedure can take anywhere from 3 to 8 minutes
depending on the tape drive and library type. During this process, I
display a "Standby" dialog with a ProgressWheel and a timer that
fires every 1500MS and simply executes x = rnd * 323232. The timer
was added based on the discussion that had occurred with Joe Huber's
original query to the list. The ProgressWheel continues to spin even
when the app is stalled. As soon as the mouse is moved or a
keystroke occurs, the app resumes.
I've requested that the report be reopened. Please add yourself if
you're also witnessing unexpected stalls.
