https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275632 Martin Birgmeier <d8zNeCFG@aon.at> changed: What |Removed |Added ---------------------------------------------------------------------------- Version|14.0-STABLE |15.1-STABLE --- Comment #13 from Martin Birgmeier <d8zNeCFG@aon.at> --- I just reran this test on stable/15 @ f1d188c4ddbf (= 15.1-STABLE) with the msync call disabled. Initially, even after more than 16 GB (the memory size of the machine, swap was removed) were written, everything seemed to go smoothly, with the resident size of cawic between 10G and 14G as reported by top(1). But then there was activity in another process, and the OOM killer kicked in, not only for cawic, but for multiple others as well: May 19 10:24:02 hal kernel: pid 10998 (cawic), jid 0, uid 0, was killed: failed to reclaim memory May 19 10:24:04 hal kernel: pid 2087 (Xorg), jid 0, uid 0, was killed: failed to reclaim memory May 19 10:24:05 hal kernel: pid 1616 (named), jid 0, uid 53, was killed: failed to reclaim memory May 19 10:24:10 hal kernel: pid 1913 (colord), jid 0, uid 970, was killed: failed to reclaim memory Conclusion: The issue still persists on 15.1-STABLE. I changed the OS version in this PR accordingly. -- Martin -- You are receiving this mail because: You are the assignee for the bug.home | help
