Package: src:xen Version: 4.8.5+shim4.10.2+xsa282-1+deb9u11 Severity: important
I'm observing an odd memory-leak like behavior for Xen's Dom0. I've been attempting to reduce the memory usage of Dom0 so, I'd been slowly decreasing the amount allocated to Dom0. Presently using "dom0_mem=360M,max:384M". Two weeks ago I noticed `xl list` was listing less memory for Dom0 than I thought I'd previously told Xen to allocate. Worse, `xl mem-set 0 384` fails to have any effect. Further observation indicates Dom0 is getting ballooned down roughly 1-2MB per day, in spite of Xen having plenty of free memory (more than 1GB is available). Just tried and `xl mem-set 0` to less than the current limit works, but `xl mem-set 0 384` merely sets Dom0 back to the previous limit. Over time this is forcing restarts of Dom0, which is Bad(tm). This is a rather serious situation. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sig...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
