(moderation:
I received a work packet and it processed fine until it reached 30% complete. They it has been with this error message. Sometimes when I check it looks like it is working, but then the error message returns, and the task does not advance.
What is the best solution to get it going again?
Thanks,

"The "Waiting to acquire
)
"The "Waiting to acquire lock" message is generated when BOINC detects that a second application is attempting to run in one of its slots. BOINC will continue trying to start the application every 10 minutes.
The task has crashed and not removed the BOINC lockfile in the slot the previous task occupied. So when BOINC tried to restart a new task in that slot, it can't because of the lockfile.
Remedy is to just shutdown BOINC and restart BOINC. That should clear the lockfile. If it persists, then open the properties of the task that is showing the error message and see what slot it is running.
Then shutdown BOINC and open that slot and delete the boinc_lockfile. The restart BOINC again.
