https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224479 Mark Millard <markmi@dsl-only.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markmi@dsl-only.net --- Comment #10 from Mark Millard <markmi@dsl-only.net> --- (In reply to Peter Holm from comment #8) I suggest seeing bugzilla 206048 about file system based swap spaces hanging up. In particular comments #7 and #8 that quote Konstantin Belousov on the subject (or reference his material). Part of the text says: As result, swapfile swapping is more prone to the trivial and unavoidable deadlocks where the pagedaemon thread, which produces free memory, needs more free memory to make a progress. Swap write on the raw partition over simple partitioning scheme directly over HBA are usually safe, while e.g. zfs over geli over umass is the worst construction. --=20 You are receiving this mail because: You are the assignee for the bug.=
