Sorry for the delay in replying. I had to give an extended run under kernel 4.2.0-rc6 to obtain comparative results. Both kernels' config files are attached. The applications running are the same both times, mainly iceweasel 38.1.0esr-3 and chromium 44.0.2403.107-1. With the rc7+ kernel but not the rc6 kernel, chromium eventually gets into a state of consuming lots of swap. I was able to capture the output requested when running a 4.2.0-rc7+ kernel (Linus' git head as of around 05:00 UTC 19 August 2015) just before swap was exhausted, forcing me to do a control-alt-delete shutdown and waiting ages. The kernel config for the rc7+ is attached The comparison good kernel is from Debian: Linux am64 4.2.0-rc6-amd64 #1 SMP Debian 4.2~rc6-1~exp1 (2015-08-12) x86_64 GNU/Linux Output of the script quoted above for the rc7+ kernel is: iceweasel 229872 kB chromium 58680 kB chromium 57956 kB chromium 55596 kB chromium 54600 kB chromium 51880 kB chromium 51552 kB chromium 46436 kB chromium 43292 kB
