Error: Shared memory connection was closed

Veeam Logoby frankive » Wed Apr 15, 2015 1:38 pm

I have a SBS 2011 server I want to protect. Trying Veeam Endpoint Backup. Backing up to a usb-drive connected mapped to B:
The 10 other servers I have tested all work fine!

The error messiage I get is:

4/15/2015 3:25:42 PM :: Error: Shared memory connection was closed. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: The system cannot find the file specified. Failed to write data to the file [B:\VeeamBackup\Backup Job DC01\Backup Job DC012015-04-15T151952.vbk]. Failed to download disk.

I can confirm the b: (usb-drive) is online and works fine.

Frank,
Thanks. The error refers to the mechanism used for components to “talk” with each other. Might be a memory overrun, but, honestly, I am just guessing now. Let’s wait for support and QA investigation.

Maybe my experience can be of any help.
Aftare replacing the USB wireless network adapter on a Windows 8.1 64bit PC I started getting the following error, similar but not identical to yours:
04/05/2015 20.05.45 :: Error: Shared memory connection was closed. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: Periodo di timeout del semaforo scaduto. Error code: 121 Failed to write data to the file [G:\VeeamBackup\Backup Job PCNAME\Backup Job PCNAME2015-05-04T195527.vbk]. Failed to download disk. (The semaphore timeout period has expired)..
I made several tests including removing and reinstalling VEB before deciding to remove the new USB wireless adapter.
At that point VEB started working again.
I presume the USB wireless network adapter is damaged because the brand and the model look to be the same as athe previous USB wireless network adapter and because the same device failed working on a Linux box (that's the reason because I swapped it with the working one).
Hope this helps...

[MERGED]Problems after upgrading to Windows 10 (maybe)

Veeam Logoby marius roma » Mon Nov 23, 2015 6:23 am

After upgrading from Windows 8.1 to Windows 10 and formatting the target USB drive I was unable to complete any backup job.
The errors I get include:

Code: Select all
22/11/2015 22.33.35 :: Preparing for backup
22/11/2015 22.35.22 :: Creating VSS snapshot
22/11/2015 22.40.04 :: Unable to exclude files from snapshot: Shadow Copy Optimization Writer timed out (see Windows event log for more info).
22/11/2015 22.40.13 :: Calculating digests
(...)
23/11/2015 5.00.40 :: Failed to backup [<filename>]
23/11/2015 5.00.55 :: Finalizing
23/11/2015 5.01.34 :: Error: Shared memory connection was closed. Agent failed to process method {FileBackup.SyncDirs}. Exception from server: Failed to decompress LZ4 block: Bad crc (original crc: 18180b2f, current crc: 59bd69bf). 
                   :: Processing finished with errors at 23/11/2015 5.01.45

I had a very similar error the night before, with the process closing while processing a different file of the same disk.
I executed chkdsk /f /r on the disk containing the file <filename> with no error reported.
Is the problem related to the installed program (should I reinstall it?), to the source drive, to the target or to what else?
Regards

What version were you running at the moment you upgrades to windows 10? Was that a supported version already? Just to verify and to be sure you aren't running v1 which doesn't work in Windows 10.

From what I can see in the snippet, it looks like there is a problem with the vss. And after that, I see an issue with a crc... If you have a supported version, please log a support case through the control panel, our support guys will need more info to figure out what and where it went wrong

Thanks

Hey guys,

Test your source disk (and target repository as well) for bad blocks with any 3rd party tool (for example http://hddscan.com/) - check disk might be not that accurate to be honest.

I made some further investigation and it looks like there was a problem with the USB ports on the PC and/or the drivers used to manage the USB disk.
I reinstalled the drivers and created a new job to copy only part of the source files and it run successfully.
I changed the settings to extend the data backed up by the job and it worked fine again.
Now it looks to work fine.
Thank you for your support.

[MERGED]Veeam Endpoint on B&R repository

Veeam Logoby Rageboom » Wed Mar 02, 2016 3:58 pm

Hi everyone,

I have a problem with a VEP backup onto a Backup & Replication repository.
I can configure my backup, but it always fails with the following message:

"02/03/2016 16:51:05 :: Error: Shared memory connection was closed. Agent failed to process method {FileBackup.SyncDirs}. Exception from server: There are no connections in the specified pool 3. "

My permissions are fine on my Backup&Replication repository.

Here are the versions of my software:
Veeam Endpoint: 1.1.2.119
Veeam Backup & Repository : 8.0.0.2084

Do you have any ideas?

Thanks!

Welcome Rageboom to the forums!

There is another thread relating to your issue over here

You may want to try and check the drivers or run a scan on the hard drive but the first thing I would suggest is going into the Control Panel of Veeam and submitting a case so they can review the log files of the backups.

Please post your case ID back here when you have it.

Cheers!

Hi.

I saw this thread but didn't found any solutions, that's why I opened a new thread :).

I opened a case from my VEP, here is the ID : 01716163.

Cheers.
