All appeared to be working correctly, but once (I did multiple test for each FreeBSD version) the FreeBSD 12.1-RELEASE-p10 behaved very similarly to what the original reported described (a moment after the snapshot has been creat= ed ping response times went to 50000-60000ms and a few lost packets, when i tr= ied http it appeared as if the server was not responsive). After net reboot all worked just fine.=20 Tried for an hour to reproduce it again, but was unable to, so I suspect it= is not only related to vmx3, but there is some other factor to it (that probab= ly changes with time) as well. The best solution would probably be to upgrade to 12.2/13.0 (as those appea= r to work fine) --=20 You are receiving this mail because: You are the assignee for the bug.=
