DS-2DE5230W-AENS Overflow problem

Hi, my name is Nelson, I'm from Argentina.
We had implemented an city surveillance security solution with 23 domes model DS-2DE5230W-AENS.
The problem is that 2 of the 23 hang up after 5 or 6 hours of work (sometimes more time, sometimes less). When crash we can't access by web or rtsp.
We have implemented the last firmware but the problem still happen.
Always we have access by ssh and when we execute a dmesg command at the last we have the next lines:

[1080735.103925] PHY: mdio0:03 - Link is Up - 100/Full

and some others commands like showStatus always response a connect failure:

# showStatus
connect failre errno=111

We think on reboot remotly by ssh but the reboot or shutdown commands doesn't be present.
I'm very sorry for my bad english
I will appreciate any help.

Thanks!
Nelson

Check all firmware is up to date, other than that go back to where you bought it from for the appropriate support.
