[DragonFlyBSD - Bug #2365] Hammer pfs-destroy and prune-everything can cause network loss

[Tim Darby via Redmine]

Issue #2365 has been updated by Tim Darby.


This is on x86_64 AMD. I should add that those swap_pager messages were happening during the pfs-destroy, but I don't know whether or not that was the trigger.  More concerning to me is the loss of network connectivity.

Fairly consistently, when I run hammer prune-everything, at some point in the process my ssh session will stop and not recover and the machine becomes unavailable on the network.  It eventually returns to normal and I can reconnect to it.  Today, I ran a hammer pfs-destroy on a 1.3TB pfs and the same thing happened.  While the network was out, it was putting these messages in the log:
