Error in inDL library/jsonlite/libs/x64/jsonlite.dll maximal number of DLLs reached

[tobigithub]

Commonly observed when calling library(DT) after number of errors invoked by third party library in prior code.

Error in inDL(x, as.logical(local), as.logical(now), ...) : 
  unable to load shared object '//R-3.2.1/library/jsonlite/libs/x64/jsonlite.dll':
  `maximal number of DLLs reached...
Error during wrapup: cannot open the connection

[tobigithub]

Still alive under R.3.3.1 and DT_0.1 and caret_6.0-70

This is an error related to 1990 Microsoft Windows DLL hell and is a R core problem which the R community was and will not be able (also not willing) to solve.

See MAX_NUM_DLLS link on Google.

#---------------------------

Possible workaround: save workspace and reload R and then execute the DT table function.
