This is likely from the return value of mclapply's FUN: 
parallel:::sendMaster tries to serialize it, and fails.

   serialize(integer(.Machine$integer.max / 4), NULL, TRUE)

do further data reduction before trying to return the results (probably 
a parallel 'best practices' anyway). Neither traceback() nor 
options(error=recover) deal gracefully with mclapply errors like this.

Hope that helps,
