DO NOT REPLY [Bug 4327] New: Sudden rsync errors
https://bugzilla.samba.org/show_bug.cgi?id=4327
Summary: Sudden rsync errors
Product: rsync
Version: 2.6.8
Platform: All
URL: http://www.ercbroadband.org
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: mhaney@ercbroadband.org
QAContact: rsync-qa@samba.org
I'm getting some unknown errors when trying to rsync between one of our
servers
and a client of ours. These errors started after this server was upgraded to
Fedora Core 5, but I've verified that the upgrade isn't the cause of the
problem as another server running RHEL AS 4 has the same problem. Below is the
last 70 lines of an strace done earlier today.

As for the client side the server is RHEL 3 and it hasn't had any major
updates
and rsync isn't being used on it's end.

------- Comment #1 from wayned@samba.org 2008-01-12 11:45 CST -------
All I see in the strace info is rsync complaining about the connection closing.
You'll need to figure out why the connection is closing, perhaps using hints
from the issues-and-debugging web page on the rsync website.
If you have further info to provide, please feel free to reopen this.
