It's helpful to know this a non-issue for you. Sometimes I feel like that "last samurai", fighting for and standing by RR/LC Empire which unfortunately is losing ground on the Linux landscape :( ...If you haven't seen this yet, the Ubuntu team finally put together a good site for third-party devs, ...

I'd be happy to donate a Linux box if they don't have one. They do have some Linux machines there, but perhaps not one with your particular config. That was my a bit of sarcasm to this sad story, as one may get an impression they don't have any. Out of 7 stock hardware set-ups (Dell, HP machines), ...

...it's a little hard to pin this down on LC if the standard drivers work... Then how to explain open-source ATi driver that causes no problems in Ubuntu 10.04, but does in Ubuntu 11+ ?? ...I suppose it's possible that after memory allocation an internal error prevents the execution of the free() c...

Could the problem lie with the NVidia driver? ... and with ATi, and with Matrox, and... ? "MetaCard is very good at exposing bugs in video drivers." Oh, that is nice quote. But it is Linux we're talking about - a big sandbox full of kids where all have to play nice with each other - and not "leak" ...

I've had good experiences with the proprietary NVidia driver on Ubuntu 11.10 and earlier. Given the wide variety of configs and symptoms among those who've tested here, is it entirely unthinkable that this may be yet another leak in Xorg, or some other component? Obviously this is not NVidia's or X...

...I've got the standard built-in graphics card, which is an NVIDIA Quadro NVS 3100M... If you have not installed proprietary NVidia driver and using system default open-source driver (nouveau), then you would not have this problem. On all my test systems with NVidia grapchics LC 5.5 works fine unt...

The problem is in LC 5.5* - not 4.* My LC 4.* works fine (apart from historically persistent performance issues which is another matter).

Well, I wasted another half hour on this and managed to get a reported leakage of 5MB after some severe stressing. That's 5 megabytes of private storage and a matching 5 megabytes of virtual storage. On a 4GB system that doesn't even register in the total current usage of 16%. I'm pretty much done ...

Just to follow up, I left that stack open all night, and checked this morning. The memory usage went up to 32%, I have 8gb of RAM, so that is quite the usage... 8GB x 0.32 = 2.56GB! But larger the screen resolution, larger the stack and the object you resize - heavier the leak. On my 2056x1600 30" ...

Ubuntu 12.04 x64 Dual Monitors Nvidia geforce 8400 card Nvidia Driver Version 295.33 LiveCode 5.5.0 ... and the memory (slowly) went up from .6 to 26.7% ... Yep. That is it. The memory leak. It should not have happened. .6 to 26.7% is huge number, you lost 20% of your RAM in few moves. 20% on, say,...

Update Tested on openSuSE 12.1 64bit on a system with nVidia graphics, all default install, and guess what? Same problem. I knew that distribution should not matter, they (mostly) all use same drivers, same X server and so on. Please, anyone, run top in terminal, select memory usage column (Shift + ...

Update.
Same problem even with open-source ATI driver (older ATI cards). Tested on Ubuntu 11.04 32bit

LiveCode 5.5.0 works fine for me in Ubuntu 12.04 using latest Nvidia graphics drivers. No noticable memory leaks. "No noticable"? If you do top in terminal, compare Xorg memory usage before and after dragging some large object (like text field) around your maximised stack for a while. This number s...

LiveCode 5.5.0 (incl. GM3) on Linux (tested on various Ubuntu installations) causes rapid memory leak to Xorg X server. Create new stack, move it around, or better create a text field, bigger the better, move it around the stack, watch (top) Xorg process eating all system memory very rapidly, until ...

Actually its all down to understanding the nature of FTP protocol. FTP, unlike HTTP uses two channels to communicate and exchange data. 1. First channel (usually on port 21) is called 'Control Channel' (PI - Protocol Interpreter). You use it to pass FTP commands to the server and server will respond...
