Veeam7 hang

Veeam Logoby maverick964_uk » Tue Apr 28, 2015 10:12 am

We have Veeam 7 patch4 installed on a dedicated HP DL380 server (24 cpus and 48GB ram).
We have 64 backups that run each night and we have 6 x HP DL380 hosts with all the same resources.

Most nights backups work fine no problem but we see odd days where everything has hung. This morning, 51 jobs were still in the running state and it would seem that they are all hanging, waiting for backup resources??

I noticed some proxy logs were reporting "Failed to process command "IsOrphaned"". What does this mean?

Proxies are set to concurrent tasks 6 however they can go to 12. Its all direct SAN mode too.
We write to NAS shares on a HP D2D. All 10Gbit networking. The two backup respositories are set to 10 for maximum tasks.

As said it all normally works but we get this complete hang 1-2 times a week. The only cure is to reboot the Veeam server.. The veeam gui works but stopping jobs shows no response...

any ideas/clues would be very helpful. thanks

Mike, have you contacted technical support with this issue? Logs investigation is definitely required here.

Hello,

Not sure, please ask our support team for assistance with reading the debug log.

Not sure I follow this statement. Do you mean that the number of tasks can be 12 even though you've configured 6 or something else?

Thank you!

yes it was set to 6 for tasks per proxy however the green tick remains like this up to 12. If we go to 13 then we get a warning sign. Should we set to 12 for each proxy?

I rebooted the veeam management server then tried to run a job. It sat there saying "waiting for backup infrastructure resources".
As I saw the IsOrphaned reported on proxy logs I rebooted all proxies. Once they all came up then veeam started working...

Looks like the veeam server had troubles with the proxies... What could cause this?

If necessary we can raise this with support...if you think we should.

You can raise it if you need to optimize your backup window by running more concurrent tasks.

Hard to say without logs reveiw.

If you see the same behavior once again, please open a case.
