in thread threads causing memory leak

do you mean you create a new thread every 30 seconds?
Yes.
Do you ever ->join that thread?
No, i wait for it to finish.
Otherwise, I think you should use async.
async?

Update:
Using async does not help, same problem. joining the thread leads to:

    That's exactly what join does. But if you don't join it, it's memory is never returned to the memory pool.

    That's a bug in Win32::GUI.

      WxPerl Windows will probably crash too. I will test it when I have some time.

        Perhaps "bug" is too strong a term. Let's call it an "incompatibility".

        The problem as I understand it, is to with static data in XS modules on modules that were never designed to work with threads. I believe that it is impossible to correct this incompatibility from within threads.

        It requires modules like Win32::GUI, Tk (perhaps WxPerl), and many others, be modified to become compatible with threads.

        I have no experience of WxPerl, but I'd bet that the same techniques I use in Re: threads causing memory leak (No leak!) would work with it also.

        For the record, it's quite possible to use Wx with perl threads. Padre does it, for example.
