[Swift-user] Block task failed: Connection to worker lost

[Yadu Nand Babuji]

Hi Jonathan,

The issue you are seeing sounds pretty close to what David reported a 
while back.
Could you send us a tar ball of your run directory from a failed run ?

Could you also check if you've set lowOverAllocation and 
highOverAllocation in your sites definition ?

Thanks,
Yadu
