<ul></ul><p>hammer cleanup is unusable until this gets fixed. I've disabled the script in periodic daily for now.</p> DragonFlyBSD - Bug #3187: Kernel: multiple swap pager messages during hammer cleanuphttps://bugs.dragonflybsd.org/issues/3187?journal_id=137792019-08-13T21:08:17ZAnonymous

<ul><li><strong>Assignee</strong> set to <i>dillon</i></li></ul><p>I am going to guess that it is an interaction with the encrypted swap that is causing the problem.</p>
<p>Try turning off encryption on your swap partition (in your /etc/fstab), reboot, and see if the problem reoccurs.</p>

<ul></ul><p>This continues to fail on a regular basis and turning off encrypted swap didn't help. Unfortunately, the nature of this failure is such that it won't allow me to get core dump. The only fix is to reboot the machine which is needed several times a week.</p> DragonFlyBSD - Bug #3187: Kernel: multiple swap pager messages during hammer cleanuphttps://bugs.dragonflybsd.org/issues/3187?journal_id=138252019-10-27T21:45:46ZAnonymous
<ul></ul><p>I was finally able to get a core dump while this was happening. I've uploaded the files to crash/bug-3187 on leaf.</p> DragonFlyBSD - Bug #3187: Kernel: multiple swap pager messages during hammer cleanuphttps://bugs.dragonflybsd.org/issues/3187?journal_id=138442020-01-15T15:35:07ZAnonymous
<ul></ul><p>This issue is not limited to hammer1. I've replaced all but one of my disks with SSDs all my volumes are hammer2 now and I've seen this same thing happen 3 times since then. Twice it appeared to happen during the nightly cleanup, but once was during the day with only moderated disk activity. This is a lot less ferquently than when using hammer1, so it's going to be even more difficult to track down.</p> DragonFlyBSD - Bug #3187: Kernel: multiple swap pager messages during hammer cleanuphttps://bugs.dragonflybsd.org/issues/3187?journal_id=138452020-01-15T15:40:44ZAnonymous

<ul><li><strong>Status</strong> changed from <i>New</i> to <i>Resolved</i></li></ul><p>I haven't seen an occurrence of this for awhile. I'm guessing that this commit fixed it?<br />git: kernel - Fix indefinite wait buffer bug with encrypted disks</p>
