Good day,

I couldn't get a working param object. It never completes the command 

param = bpstart(SnowParam(2, manager.hostname = "", manager.port = 2559))

I obtained the IP address by typing "My IP address" into Google and it gave me the address shown. I used netstat -an and 

  Proto  Local Address          Foreign Address        State
  TCP              LISTENING

was one of the results displayed. I have reproduced this problem on another computer with Windows 10. I also tried

param = bpstart(SnowParam(2, manager.hostname = "", manager.port = 2559)) but it doesn't complete.

I was able to identify the problem is with the line

bpbackend(x) <- do.call(parallel::makeCluster, cargs)

So, to summarise,

> cargs
[1] 2

[1] "SOCK"

[1] "C:/Program Files/R/R-3.5.0/library/BiocParallel"

[1] ""

[1] 2559

> do.call(parallel::makeCluster, cargs) # Freezes.

Should I ask the question on R-devel because it doesn't appear to be specific to Bioconductor ?
