BE2012 SP1a High Memory usage and hanged

[demo4119]

Current setup : -

Windows 2008 R2 SP1

BE 2012 SP1a ( CASO)

CPU : Quad Core

Ram :50 GB

Deduplication folder size : 30 TB

Windows 2008 R2 SP1

BE 2012 SP1a - Media server

CPU: Quad Core

Ram :50 GB

Deduplication folder size : 30 TB

When there are 6 concurrent backup running on the CASO on the Vmware virtual machines backup the memory usage will reached 100% and backup jobs will failed or backup server hanged. While backup of from the BE media server with 6 concurrent job on physical server via BE agent dont have this issue.

We have also disable the antivirus from scanning the BE processess , MS SQL databases and deduplication folder mount point based on symantec best practise.

Below are the technote that is related to my issue without any resolution yet other that restart BE server services after a few backup .

Beserver.exe is using up all available RAM(Memory) until the service is restarted in Backup Exec 201...
This issue is resolved in Backup Exec 2012 Service Pack 1a. (TECH186717)

would recommend to open a support case

[demo4119]

Case has been opened and getting support to look into the issue. We have also reduce the concurrent backup jobs from 6 to 3 and problems still exist. There are 2 BE server ( 1 CASO and 1 Media server). We dont have any issue when media server backup phyiscal server as BE agent but this issue will only happend on CASO server which backup the current Virtual machine reside on ESXi 4.1. When ever we hit the backup slowness we tried to restart BE services and it may or may not work.

[demo4119]

has logged a case with support and found that backup of Virtual machine (ESX) via network mode with Differential wont has it slowness or hanged issue . But when the differential backup via San mode to Deduplication folder we will hit the issue and currently symantec backline engineer is working on the dedug log to find the root cause.

I can confirm this

- BE 2012 SP1a with all hotfixes

- win 2k8 R2 with all hotfixes

After every Job, some memory is hold back. It may be related to copy-jobs. We start D2T Jobs at 2pm. As you can see in the picture, memory usage grows from this point.
