Hi Tom,

Thanks for the reply,

Well, I think I *might* have narrowed it down. I think it may be worth a post on the cpan forum site for the module. I didn't go to the debugger, but I did do some incremental code removal in the Linux version.

It *looks* like Text::Compare is leaking badly. I removed the call to that and that appears to have stabilized the memory at more or less the same as on AIX. What's interesting is to figure out why the difference.

I thought it could be a version problem, but, no, the module versions look the same.

Anybody else hit that?

Kind regards, Derek.
