Issue #3187 has been updated by t_dfbsd.
I was finally able to get a core dump while this was happening. I've uploaded the files to crash/bug-3187 on leaf. ---------------------------------------- Bug #3187: Kernel: multiple swap pager messages during hammer cleanup http://bugs.dragonflybsd.org/issues/3187#change-13825 * Author: t_dfbsd * Status: New * Priority: High * Assignee: dillon * Category: * Target version: ---------------------------------------- On master, commit a19800f223, running hammer cleanup causes dozens of messages like this and causes the machine to become inaccessible by network services, SSH in particular, although ping still works: May 23 19:20:14 <kern.crit> boojum kernel: swap_pager: indefinite wait buffer: bp 0xfffff800735334d8 offset: 5092941824, size: 4096 m=0xfffff8005fee7580 busy=e0000000 flags=00004080 This behavior was also observed at commit d29a2431b3, so whatever is causing it is probably earlier than that. When I ran hammer cleanup today, the last thing I noticed running before my SSH connection died was hammer reblock-btree. This was on a 8TB encrypted volume. ---Files-------------------------------- dmesg.boot (88 KB) fstab (976 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.
