[Networker] save.exe shared memory crash on Windows 2003

Hi,



We are seeing save.exe crash (sometimes) when doing a block level backup,
and was wondering if anyone has run into this.



Configuration:

Windows 2003 32-bit (20GB RAM—appeared to be accessed via PAE)

NetWorker 7.5.4.1

Using Timefinder to snapshot Symmetrix volume, and back up at a block level
using save command on the backup server (save -c <clientname> -e "4 Days" -s
<nsr_server> -b "weekly" -N <clientname>-D_<arrayed>:B12_\\.\PHYSICALDRIVE13
-LL \\.\PHYSICALDRIVE13)



Error:

Some backups fail with the following error, which we captured via “save –D9”
debug option. Many succeed, and most succeed upon add’l attempts.



Save –D9 shows the following:

Thoughts:

1.       Remove RAM, could be an odd interaction with PAE memory access
mechanism. We are going to try to get the system down to 2 or 4GB of RAM.

2.       Disable any unnecessary processes

3.       Continue to work with EMC support, they are still working on
determining what the error indicates.



Anyone have any other thoughts?



Thanks,
