Hi all,

my package recently got accepted and moved to the Bioconductor repository.

Suddenly I get an error during the package build for Linux and OS (the INSTALL is working). The error occurs during the creation of the vignette in a chunk. The error was not there before and I can't reproduce it on my local machine:

" Error in serialize(data, node$con, xdr = FALSE) :
error writing to connection
Execution halted "

Interestingly I get the same error in totally different points for Linux and OS.

I am using BiocParallel with BPPARAM = BiocParallel::MulticoreParam(workers = 5) and requested 5 CPUs. Can it be that I am not supposed to use that many CPUs? Did anyone encounter a similar issue? Should I avoid parallelization in the vignette or should I just reduce the number? The dataset I use in the vignette is a small one, so I suppose it is not a memory issue.

Thanks for any suggestion,

Carmen
