how many netcdf files can be opened at one time?

Dear everyone,

I have a list of files named by the date, for example, 1900-01.nc, 1900-02.nc, ... 1999-11.nc, 1999-12.nc, 1200 files in all. I'd like to open them by using the addfiles() function, the script is the followings,

   fns = systemfunc("ls 19??-??.nc")
   in = addfiles(fns,"r") ; open netcdf file
   ListSetType(in,"cat") ;specify type of merge

There is an error message,

fatal:Too many open files

it seems that there is a limit for opening NetCDF files in NCL. Is that so?

Thanks.

Xuguang SUN
