For starters:

  What OS and version is the rsync script running on?

  Which end do you have to reboot?  The machine running the script,
  or the Gentoo Linux?

  What versions of rsync are running on each end?

  Can you show the command line that fails?

  Based on the mention of multiple terminals, it sounds as if you
  have a fairly complex ssh environment.  Can you get it to fail in
  a simpler environment, ideally with only one terminal?
