I see, thanks!  I still need help though.  Do you suspect the application?

The "bad" version has: 
  5632 rclone   RET   fork 0
  5632 rclone   CALL  sigfastblock(0x1,0x82ac02038)
  5632 rclone   RET   sigfastblock 0
  5632 rclone   CALL  thr_self(0x7fffdf9faed8)
  5632 rclone   RET   thr_self 0
  5632 rclone   CALL  sigaltstack(0,0x7fffdf9fae98)
  5632 rclone   RET   sigaltstack 0
  5632 rclone   CALL  sigaltstack(0x7fffdf9fae60,0)
  5632 rclone   RET   sigaltstack 0
  5632 rclone   CALL  sigprocmask(SIG_SETMASK,0x7fffdf9faea8,0)
  5632 rclone   RET   sigprocmask 0
  5632 rclone   CALL  read(0x8,0xc000600000,0x21000)
  5632 rclone   RET   read -1 errno 35 Resource temporarily unavailable
  5632 rclone   CALL  close(0x8)
  5632 rclone   RET   close 0

Whereas the "good" version has:
  5640 rclone   RET   fork 0
  5640 rclone   CALL  sigfastblock(0x1,0x82ac02038)
  5640 rclone   RET   sigfastblock 0
  5640 rclone   CALL  thr_self(0x7fffdf9faed8)
  5640 rclone   RET   thr_self 0
  5640 rclone   CALL  sigaltstack(0,0x7fffdf9fae98)
  5640 rclone   RET   sigaltstack 0
  5640 rclone   CALL  sigaltstack(0x7fffdf9fae60,0)
  5640 rclone   RET   sigaltstack 0
  5640 rclone   CALL  sigprocmask(SIG_SETMASK,0x7fffdf9faea8,0)
  5640 rclone   RET   sigprocmask 0
  5640 rclone   CALL  read(0x8,0xc0006c6000,0x21000)
  5640 rclone   RET   nanosleep 0
  5640 rclone   CALL 
compat11.kevent(0x5,0,0,0x7fffdfffd698,0x40,0x7fffdfffd670
)
  5640 rclone   STRU  struct kevent_freebsd11[] = {  }

So the read(8, ...) is what is failing.  Finding this in net/rclone will be a
challenge...
