In my case, the machine I upgraded the OS on worked rock solid for 4 years. Thus, the upgrade is clearly the cause of the timeouts, as I observe.

I had the same issue for a while on FreeBSD 11.2 and 11.3 with Supermicro and DELL servers:

fixed with
Code:

and power cycle for at least 3 days.

Does anybody have this problem after updating to FreeBSD 12.1?

Using vfs.zfs.cache_flush_disable: 1 solved problem for me but caused some performance degradation.
