error in champ.norm, Error in serialize(data, node$con) : error writing to connection

I run R package champ. There is an error, when normalized data. I don’t know what’s wrong. Tian The R code is as follow:

`> myNorm <- champ.norm(beta=myLoad$beta,
arraytype=”EPIC”,
method=”BMIQ”,
cores=20,
plotBMIQ=TRUE,
resultsDir=”/home/user/guoyu/methylation/2.preprocess_result/normalization”)

[===========================]

[>>>>> ChAMP.NORM START <<<<<<]

champ.norm Results will be saved in /home/user/guoyu/methylation/2.preprocess_result/normalization
[ SWAN method call for BOTH rgSet and mset input, FunctionalNormalization call for rgset only , while PBC and BMIQ only needs beta value. Please set parameter correctly. ]

<< Normalizing data with BMIQ Method >>
Note that,BMIQ function may fail for bad quality samples (Samples did not even show beta distribution).
20 cores will be used to do parallel BMIQ computing.
