Therefore all other workers, when trying to read, report that the file is unaccessible.   You could try to designate one worker for the reads, i.e. use something along the lines of      fetchfrom 1 dset fid  punkty  string i     You could alternatively try to open the file on all workers - which should be ok if all accesses are read only.
