https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250388 Mark Millard <marklmi26-fbsd@yahoo.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |marklmi26-fbsd@yahoo.com --- Comment #2 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to igor.polovykh from comment #0) > . . . killed: out of swap space If your console messasges do not include messages about "swap_pager_getswapspace(...): failed", then it is unlikely that being out of swap space is the actual issue even when it reports: "was killed: out of swap space" messages. For such contexts, making the swap area bigger does not help. In other words, "was killed: out of swap space" is frequently a misnomer and not to be believed for "why" the kill happened or what should be done about it --without other evidence also being present anyway. Do you have "swap_pager_getswapspace(...): failed" notices? The answer would likely guide what sorts of things would be appropriate to avoid the "killed: out of swap space" events. FYI: Other causes of the kill events include . . . Sustained low free RAM (via stays-runnable processes). A sufficiently delayed pageout. The swap blk uma zone was exhausted. The swap pctrie uma zone was exhausted. (stays-runnable processes are not swapped out [kernel stacks are not swapped out] but do actively compete for RAM via paging activity. In such a context, free RAM can stay low.) --=20 You are receiving this mail because: You are the assignee for the bug.=
