Re: IFS files

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Mike,

IBM provides an API called tmpnam() (external name is _C_IFS_tmpnam) 
That will generate an IFS file with a unique temporary ("random") name. 
 The idea is to allow multiple processes to create IFS files in the 
same /tmp directory without their names conflicting.  The API ensures 
that the names are unique.

Although yours may all start with 'QACX', I don't think that is 
guaranteed.  I think the names can be different than that if you 
generate enough files.

So I suspect there's an application on your system that is doing 
something like (this is RPG code, but it could be any language, of course):

  tempfile = %str(tmpnam(*omit)) + '_wbsm';
  x = open(tempfile: ...etc...)

I guess what i'm driving at here is that searching on the filename is 
probably going to be fruitless since these are temporary names generated 
by an API that generates random filenames.

But, likely, some process during your startup is creating them and using 
them for something.  The "wbsm" is likely the best clue you have.  Maybe 
look at the characters "wbsm" and see if maybe you have something 
starting that these characters would make sense for.

Good luck.
