Mini XL+ flushcache48 timeouts

[macnugget]

I have a newly-purchased FreeNAS XL Mini+, purchased diskless, with 8x10tb Seagate Ironwolf drives (ST10000VN0004-1ZD101) set up with in a single raid-z2 pool. I deployed it on September 10 and it's been online and running continually for the past two weeks.

I am seeing infrequent, periodic errors in the kernel log, all of them looking like this:

Code:

freenas ahcich2: Timeout on slot 4 port 0
freenas ahcich2: is 00000000 cs 00000010 ss 00000000 rs 00000010 tfd c0 serr 00000000 cmd 0004c417
freenas (ada2:ahcich2:0:0:0): FLUSHCACHE48. ACB: ea 00 00 00 00 40 00 00 00 00 00 00
freenas (ada2:ahcich2:0:0:0): CAM status: Command timeout
freenas (ada2:ahcich2:0:0:0): Retrying command

This is not a common occurrence, I only see 34 times that it's happened in two weeks. Four different devices have had the issue. ada0 (10 times), ada1 (8 times), ada2 (3 times) and ada6 (13 times).

SMART scans all look happy and I haven't seen any evidence of any other problems on the server.

Is this something I should be concerned about? Any suggestions for things I should be doing? Thanks.
