ZFS errors and timeouts and CIFS problems

[luma]

Hello everyone,

I built a Nexentastor Community Edition server and it has been running quite well until recently.

I started noticing when using Cifs (mainly when using XBMC to watch TV or when streaming on my desktop with zoom player) it pauses/stops and I lose the connection to the server (but only CIFS, seems like Gui keeps working and ISCSI seems fine)

I checked the logs and I do see a ton of these at about the right times:

Server Specs:
Intel E3-1220
Supermicro MBD-X9SCM-F-O
4x Kingston DDR3 4GB ECC Unbuffered ram
6x Seagate 1.5TB
1x IBM BR10i with the non-raid firmware (found on these forums)
2x 80GB Seagate laptop drives
Nexentastor 3.1.2-8147 (r9697)


Any ideas what is going on?

One thing to note is when this problem happens I can normally get to the web gui and also my ISCSI connection stays active and the VM's running within another server with ISCSI to this fileserver are just fine.

Thank you much in advance.

Good Evening.
