@ERROR: setgroups failed

[Randy Vinas]

Hello.  We have a few OS X machines running Jaguar 10.2 that's set to 
rsync over important files for backup purposes. The rsync was happening 
without any problems until the last Jaguar security update was installed 
a few weeks ago or so. Now they are giving the below errors and the 
rsync does not happen:

@ERROR: setgroups failed
rsync: connection unexpectedly closed (78 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(190)

The machines running Jaguar are running rsync version 2.5.7 with the 
exception of one computer, which is running rsync version 2.5.2. Would 
anyone have any ideas on a resolution to fix this problem?
