The freebsd-arm-paulzhol failure looks real, and may be related to #57476 (attn @paulzhol; CC @neild).
See previously #38413.

The other two are #58168.

I'm not sure whether this failure mode is fixed by CL 483116. (I suspect not, because the two failures with this signature are in the /h2 subtest, and IIUC that fix only really affects HTTP/1.)
