Encoding problem with HD cams - SOLVED -

[licchende]

Dear all
It's my first message on the board but i'm quite sure not the last

From time i'm playng with zoneminder and last week I setup a very strong system with 9 2MPX H.264 cams (1600x1200) in mocord.
The server it's a Intel I5 Quad Core with 4GB of RAM, 2TB HDD, gigaeth, Ubuntu 12.04 lts ( before just shell and now with Lubuntu) and ZM 1.25
Cameras are connected with a hyperlan 300Mbps network...
I take for this work n.5 2MPX cameras 1600x1200 ( china but very very nice) and n.3 Vivotek 8161 2MPX 1600x1200, both configured with 5FPS and H.264 codec.

All seems to work perfectly with console load of almost 5%, but sometimes I can found events from encoding errors like this

I have tried to update ffmpeg
to modify shmax to 1GB but nothing can help to to solve...
I exclude hyperlan network because 2 cameras are directly connected to the server but with same encoding problem.
Zoneminder's log it's clear from error...
Can someone help me to found the trouble?
Could be too less powerfull the CPU for 9 hi res mocord channel???

What You think about?

[hk_niko]

maybe is the ram...because you have almost all the RAM occupied...try increasing the ram...
Also do not open the montage or individual cameras directly from that server, because the display would flash to overflow the CPU and RAM

SOLVED
After I have forced on the system to work only with TCP connection oriented flow everything start to work very well also if the ram it's almost fully occupied

For sure It work with UDP connectionless protocoll by default and H264 don't like it.

No I've another trouble, but for this It's helpfull another title
