System process 50% CPU during backup then server locks up
Posted: 20 Apr 2012, 18:06
Windows Server 2008 SP2 64bit 16GB RAM
Firestreamer 3.3.0 x64
DPM 2007 SP1 w/ KB959605 & KB976542
To improve backup time to "tape" (was using USB) I have installed an ESATA card (SiI 3132 chipset) in the DPM server (Dell PowerEdge 2950). This has vastly improved backup times, but only when the server doesn't lock up with the System process pegged at 50%. Roughly 300GB can be transferred to the ESATA drive before the server becomes glacial in response, requiring a hard reboot (attempting proper shutdowns or reboots haven't worked).
I've waited 5 hours with the System processed at 50% CPU and haven't seen this issue resolve itself.
This issue has occurred when DPM is only performing a "tape" backup; no recovery points or synchronizations being done by DPM.
System process CPU usage ramps up once the backup begins.
Has occurred with two different ESATA drives (LACIE 2TB Rugged XL).
Besides trying a different ESATA card with a different chipset I’m not sure what else to look at here.
Pre-thanks for any thoughts, pointers, etc.
