[R] problem with package doMC: ignoring SIGPIPE signal

[Jannis]

Dear R users,


since I updated to R-3.0 I get some error messages while using a 
parallelized process with the packages foreach and doMC.

The error message is:

Error: Error in sendMaster(try(lapply(X = S, FUN = FUN, ...), silent = 
TRUE)) (from doMC.R#170) :
   ignoring SIGPIPE signal


The stack saved with dump.frames and loaded via debugger() is:

Available environments had calls:
1: #3: do.call(paste(algorithm.type, "Ncdf", sep = ""), call.args)
2: gapfillNcdf(amnt.artgaps = list(list(c(0, 0), c(0, 0))), amnt.iters = 
list(
3: gapfillNcdf.R#427: do.call(.gapfillNcdfDatacube, args.Datacube)
4: (function (args.call.SSA = list(), calc.parallel = TRUE, datacube, 
datapts.
5: gapfillNcdf.R#837: foreach(i = 1:max.cores, .combine = rbindMod, 
.multicomb
6: do.R#171: e$fun(obj, substitute(ex), parent.frame(), e$data)
7: doMC.R#170: mclapply(argsList, FUN, mc.preschedule = preschedule, 
mc.set.se
8: lapply(seq_len(cores), inner.do)
9: FUN(1:4[[4]], ...)
10: sendMaster(try(lapply(X = S, FUN = FUN, ...), silent = TRUE))
11: #20: dump.frames.mod(file.name = file.name, file.results = file.results)

Up to position 5 these functions are my personal functions that set up 
the process. I can only debug this error via dum.frames as I run it non 
interactively on a cluster machine. When I start the foreach loop 
manually from within the debugger() environment, I can not reproduce the 
error.


Does anyone have a hint on how to find the cause of this error?



Cheers
Jannis
