Re^2: Firefly Bug

My OS is CentOS5.
There is no input/output as the bug is non-reproducible, i.e. the same input on the same machine run normally when started again (after killing deadlock in say infinite loop script with one job). The hyper-threading is off on our cluster but I use it 'on' on my workstation (CentOS5) where haven't met the bug (there is only 1 firefly on 2-CPUs as 2+2 with hyper-threading slightly slowdown calculations). I think, however, that developers can fix a problem adding an explicit initialization of all semaphores (I use dlb but within the same node only) in SCF routines.
P.S. the only significant difference I can find between clusters nodes and my workstation is a RAID that is absent on nodes. Cant it be IO races in SCF initialization?
Alex.
