[Opensim-users] IAR Load error - magic # in GZip header not correct

[Fleep Tuque]

For reference in case anyone happens upon this post later, the issue was
that the hard drive on the FleepGrid server was failing, which I assume
corrupted the IAR files that people were trying to download.

More details on the recovery/restore process (and some data loss) at:
