Potential bug with Windows VM backup: "Body Timeout Error"
-
@nikade Hey Nikade,
Did you try to create a new job that will do a new chain ? Just for test.
-
@Pilow We tried that as well, same problem
Also tried with a VM on the same newtork, just another VLAN, and we're seeing the same thing. At first we figured it was because one of the xcp-ng's was on a remote site which is connected through an IPSEC VPN, but that wasn't the case.
-
Reviving this one because it never really got a clean ending. The fix for the Body Timeout Error on full backups went into xapi-project/xen-api#6786 and shipped with the March 2026 8.3 maintenance updates.
@nikade, back in March, you mentioned still hitting it on both Linux and Windows VMs even after updating. Is that still the case for you on current versions? And anyone else who landed here: are you still seeing it, or did the update sort it out?
Mostly trying to work out whether there's still something to chase or whether we can call this resolved. I'm not deep enough in the backup internals to say for sure, so your real-world results would tell us far more than anything I could guess. Thanks!
-
I need to update a few things and then I plan on trying to see if this was fixed for me. I think I only had 2 Windows machines that were a problem, and only on machines that had a larger disk and were basically empty. The counting zeros seemed to lead to a time out. Just haven't had the time to look at much of anything lately.
-
@poddingue My colleage managed to workaround the issue by re-installing the lab on other hardware, I think it is now Cisco UCS-servers. It was HP ProLiant-servers before.
Maybe it was an issue with some of the NIC or firmware, im not really sure, but it works now.
-
I get this error with each metadata backup run, but every time it fail on different pool. Only 1 failed pool at once.
-
@Tristis-Oris Hi,
Can you upload your complete logs from one of these jobs, please? You can DM me if you prefer
-
@poddingue I have asked our engineers for feedback. We have left one big VM with 1TB empty disk - and full backups are going without errors for one week.
So it seems issue is resolved.
I have to mention that during this time we have migrated to XCP-NG 8.3. and are using one of the latest XO builds. -
That's excellent news, thanks a lot for the feedback!

commit 63f8d, (Ronivay script)
Got this error on my test ofTWINSTOR: next gen 2 nodes HCI
First I ran the job manually (metadata and config), OK
Then the scheduled job ran with this error on the metadata.
{ reportWhen: "failure" } id "1783045813184" jobId "e664efb6-9514-4e6b-8303-f236ad4dbfb9" jobName "twin-conf" message "backup" scheduleId "d343fdd7-9dde-4695-adec-ba2eb43f23d2" start 1783045813184 status "failure" tasks [ {…}, {…} ] end 1783046114017 result { message: "backup task failed with undefined error", name: "Error", stack: "Error: backup task failed with undefined error\n at forwardResult (file:///opt/xo/xo-builds/xen-orchestra-202607020951/pa….runJobSequence (file:///opt/xo/xo-builds/xen-orchestra-202607020951/packages/xo-server/src/xo-mixins/jobs/index.mjs:339:7)" }Config seems to be OK
-
Hi,
Would be nice to have the entire log
Could it be possible that the master or the pool was not reachable at the time of the metadata backup?
