Asigra Reporting “Cannot Allocate Memory” During Seed Import

We have DS-Systems running on Linux and we connect the Windows Seed backups to a Windows 7/8.1 machine and then use CIFS to mount the Windows share to Linux. The command we use on Linux to mount the Windows share is:

mount -t cifs //<ipaddress of windows machine>/<sharename> -o username=administrator,password=xxxxxx /mnt/seed

We were importing some large backup sets with millions of files and started noticing “cannot allocate memory” errors during the seed import process. When the import would complete it would indicate that not all files were imported.

At first we thought this was an Asigra issue, but after much troubleshooting we found this was an issue with the Windows machine we were using and was related to using the CIFS protocol with Linux.

A sample link to the issue we were seeing is: http://linuxtecsun.blogspot.ca/2014/12/cifs-failed-to-allocate-memory.html

That link indicates to make the following changes on the Windows machine:

regedit:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\MemoryManagement\LargeSystemCache (set to 1)

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size (set to 3)

Alternatively, start Command Prompt in Admin Mode and execute the following:

reg add “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management” /v “LargeSystemCache” /t REG_DWORD /d 1 /f

reg add “HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters” /v “Size” /t REG_DWORD /d 3 /f

Do one of the following for the settings to take effect:

Restart Windows

Restart the Server service via services.msc or from the Command Prompt run: ‘net stop lanmanserver’ and ‘net start lanmanserver’ – The server may automatically restart after stopping it.

After we made these changes the memory errors were resolved!
