I am getting this error trying to get DATE from file in dir. and delete any files older then 4 days.

r=stat(FileName)
s=split(FileName+"///","/")
Server=s[4]
Graph=s[6]
User=s[5]

emit *
override emit FileDate=date(str(r[1]),"E")
emit Server
emit Graph
emit User
emit Size=r[0]

Here is my 4 days older filter

emit *
where FileDate.dateAdjust(4) < date()

Did the error message include a line #?
It's likely that the error is one of these 3 lines:
Server=s[4]
Graph=s[6]
User=s[5]

If FileName does not include all three pieces you're looking for, the error could be coming from there.
You may need to filter out some filenames before you try to parse it this way, or use this:
s=split(FileName+"//////","/")

You can also check the length of your list "s" before you attempt to access the items in the list.

slength = s.len()

if slength <= 7 then
{
Server=s[4]
Graph=s[6]
User=s[5]
}

I am selecting over 80K files and Looks like my problem is in r=stat(FileName)
One of the stat items witch containing 3 long integers is NULL, how can I get date for my next node to select any file older then 4 days if I can't read stat.

When you look at that file on the system does it have a date? If it's only 1 files out of 80,000 I would recommend just skipping that file until you are able to determine the reason that it does not have a date.

Yes, the file has a date. The STAT() function is returning a single value of null, instead of the proper value of a list like {null,null,null}

This has been reported as a bug on case CS-7548
