(First post here and an R newbie. Glad to follow protocol.)

A quick Google search of multiple lists, and a local search of downloaded
hpc archives, doesn't show a thread focused on the symptom of snow crashing
on Win7. I don't know where else to look, though I can tell that other
people are finding similar symptoms.

SNOW crashes or hangs the Rgui when my script tries to create processes on a
Win7x64 box. A colleague has the same script running successfully on Ubuntu
and WinXP. Sample line is:

clust <- makeCluster( 2, type = "SOCK",
outfile="C:/Windows/Temp/snowlog.txt" )

The malfunction occurs so soon after that line of script is invoked that the
outfile does not appear on the disk. In the Performance Monitor the Rgui
goes to zero CPU utilization almost immediately.

List searches show the most likely root causes that the community has
identified, such as an anti-virus or firewall conflict. (No luck.) The
community recommends including "manual = TRUE" to see how the package calls
up subprocesses on the box, but that's where my R skill hits the wall. Even
still, the fact that Rgui goes to zero cpu and the log file never appears
suggests that user isolation of the problem might not even be feasible.

I've also tried: removing all versions of R, deleting the R folder to take
out the packages and then installing the latest R. The fresh installation
"works" as far as it goes, but then the script produces the same symptom.

The script has previously worked on this box, so maybe a Win7 patch blew
away an undocumented dependency? But I would expect to see that in the
community chatter and don't.

Again, just looking for a trailhead. And glad to be a responsible list
member.
