<div>i´m sure this is no rsync issue. i guess rsync is just triggering it.

<div>maybe clocksource=jiffies or nohz=off is worth a try to see if it makes a difference</div>

<div>you mean, when the hang appears, you get ping timeout from another host, i.e. it`s not only userspace which is being locked but the kernel also locks up completely (i.e. does not respond to ping anymore) ?</div>

<div>I've tried to keep it as simple as possible considering...</div>
<div> </div>
<div>Various remote hosts(running rsync daemon)</div>
<div>-></div>
<div>HOST A(rsync pull / backup-dir=NFS host)</div>
<div>----></div>
<div>HOST B(NFS export for backup-dir)</div>
<div>----></div>
<div>When HOST A is done pulling the data from the various hosts a second script starts and rsync's(push) to HOST C. Every other time HOST C grabs a fresh copy directly from the remote hosts. Of course, this part is never automatically achieved since I'm never around to key "waking" the system from the console. So every time I walk by I hit a key and it keeps going.</div>

please provide the command which works and which not.</blockquote>
<div>hangs with: -avS --exclude-from=exclude.rsync --delete --backup --backup-dir=/path/to/nfs on HOST B/date +today's date</div>

<div>does not hang with: -avS --exclude-from=exclude.rsync --delete --backup --backup-dir=/path/to/local/date +today's date fs on HOST A</div>

so - resuming from hang is all about keypress?</blockquote>
<div>Yes. </div>

that sounds like an interrupt issue,i guess its no rsync problem but it`s only being triggered by rsync.</blockquote>
<div>My assumption is also that it's likely not directly related to rsync. I was thinking more NFS though. </div>

keep an eye on /proc/interrupts.</blockquote>
<div>Interesting. Hadn't thought of that. I will. </div>

please post the answer to the rsync list, so others can also have a look</blockquote>
<div>Done. </div>
<div> </div>
<div>Question: I'm running this in cron as root. Although root can rw to the NFS share while I'm in the console, is it somehow possible I'm encountering a permissions issue and just not seeing a "permission denied" anywhere? </div>
