ash ignors somtimes commands

[Miroslaw Dach]

Dear All,

	I use busybox based root-file system on my PPC405 processor 
embedded system. My root file system is mounted via NFS. I have chosen ash 
as a shell.

ash works fine but from time to time it ignores commands which I type.

For example in most cases when I type 'ps' I get a complete list of
processes. Sometimes 'ps' does not print any thing.  It is the same with
all other commands. I have written 'all' because I have also my own 
programs which seem to be not execute (sometimes) when I type their names 
and press ENTER.

Does anybody have an idea why it is so?

Best Regards

Mirek
