As Kevin said, there may be a leak in one of the method calls inside the script. And there are 104 calls. Andrei I think that's the point. It's your task to find out which (if any) of those 140 calls is causing a leak. If you can demonstrate a clearly defined reproducible problem it will get dealt with. If the short script needs to run in a loop that can be arranged or the script can repeat the action if that is what is causing the problem. It's also possible that in simplifying the script you will find an error you have overlooked. In my experience, there's no better way to find a bug in your own software than to draft a detailed bug report about it being due to the other software you are using. As Sven said , there is little point in continuing to discuss this until you can provide something clear and reproducible. I have 630 lines with 140 calls that has a bug but I cant show you clearly will not get dealt with. /gg -- .*. /V\ (/ \) ( ) ^^_^^ ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

The script that is causing problems has 630 lines of code. Do you want me to copy-paste it here, in the body of the email? Sending attachments to a list is not a good idea. I don't think this list allows it either. You can post a pointer to a script that people can download and look at. Since you are talking about scripts that are used as part of your companies business, you may not want to make those scripts public. As I worked on those scripts, I already have copies of them. If you remind me which of the three scripts (newimage, newimage5, or logov1) is the one used most, I can do some testing at my end. I will try to isolate the leak to a small set of operations or a specific API call. I would be doing this on a volunteer basis as my free time permits (mainly weekends and possibly some evenings) in order to help see that a problem in gimp-perl, or GIMP, gets found and fixed. -- Cheers!

I ran into a similar thing some time ago, working with a modified version if gimpressionist that created and deleted lots of images. I think probably there is a bug somewhere responsible for it, but I never managed to figure it out. In any case, of course, Gimp 2.2 is no longer maintained and won't be fixed.
