I am using a ZFS configuration with my NAS.

More or less for testing and as a proof of concept, I created several ZF S datasets and a ZFS volume a few nmonths ago.

My special problems seems to come from one of the datasets named 'BACKUPS'. This dataset is shared as a CIFS share.

The next thing to remember is the ZFS dataset which is exposed via iSCSI.

Both are used as a disk based backup device by backup exec.

Backups to the ZFS volume/iSCSI seem to work fine.

Another thing is usinge the CIFS share as a backup:
After some time or different Gbs backed up I see sudden reboots ! Therefore the backups fail with "unexpected network errors".
So far, I was not able to find any reason.

For me the ZFS seems to be okay.

Also I managed to get persistent log. But theres is nothing special right before the reboot.

Only strange SMB messages

Can someone help me ?

What are the device names of your ethernet interface(s)?

Posted: **09 Feb 2015 22:23**

There is only one: em0

Posted: **09 Feb 2015 23:26**

Please post your system specs (firmware, hardware, etc)

It is a HP N54L with 12GB ECC-RAM; Build is 1283

The only thing I have seen is as slowly but constant rising µC-Temp while doing the backups;
Yesterday it ended up with 50.7° C but no reboot was seen. (Which is new )

AFAIK N54L does not normally support more than 8GB Ram.
There are configurations with 16GB Ram that work without issues, but with specific Ram types.
Perhaps you could leave it with only 8GB ECC and see what happens?

If Memory is healthy, than it's a swap issue.
I wrote about it in the german section of this board: viewtopic.php?f=29&t=8229#p50248

It has been several weeks since my last posting:

As staded before, i ran a config with 12Gb (4+8) ECC-RAM and had sudden reboots only during Long backup sessions.
The reboots came at varying moments of the backup, sometimes a few minutes after start, sometimes 2 hours later.

I was ordered to run memtest to find RAM-issues. Nevertheless I did so and memtest succeeded with standrad config.

I was thinking it is not a RAM-issue, but then tried the "F2" Option in memtest which uses all CPU-cores - and the Computer freezes after 8 or 9 minutes!

The I removed the 4G RAM - same Problem
Only with the original 4G RAM-stick memtest succeded under all conditions - and the reboots no more occurred.

Are there RAM-Settings available which make my 8G RAM-stick work ? It is a Kingston stick with same specifications than the original 4G

I have a HP N54L

A lot of branded computers have specific (and non-published) memory requirements. According to Kingston, it only supports the KTH-PL316E/8G or the KTH-PL313E/8G so if it is not one of those...

It also supports the KTD-PE313E which I am guessing are exactly the same memory, validated for Dell poweredge servers.
I have those in my backup NAS (n40l) - I currently have one dimm, but had two for almost two years- and facing no issues whatsoever. ..
