I think we have a small memory leak each time a new application starts, but it's on the order of 1k per application -- any leak is a bad leak, but we're definitely seeing different memory footprints on our different kernels.

If anyone out there is running 1.2.10 and *not* seeing the memory leak, that would be handy as well as any information from anyone running > 1.2.10. Tom> I running on a 486/66 with 16 Megs, Tom> ATI Mach32 Graphics UltraPro with 2 Megs, and Slackware Tom> 2.3.0. Mat and I both use ATI Mach32 cards on 90 MHz P5s. Mat's machine has 32 MB, mine, 24.

Too early to tell whether the kernel hypothesis is true, but if it is, and it's our fault, you can see how this could have slipped by. --Cliff ctm@ardi.com
