1. at night times when load is less
2. less files are given as input

it gives error for 2000 files as Connection reset by peer: socket write error

Answer 1

The server is closing the socket, probably due to an overhead (too much connections or something).

You should post this to SuperUser or ServerFault, to learn how to increment the treeshold you are hitting, whatever it is.

Answer 2

If you are on any Unix, check the file descriptor limit with ulimit -n . Chances are it's 1024 or something like that.
