monitor keep dying

[shadowbgd]

I'm going crazy. I have DVR card (AOP BC04 model) with 4 x SAA7130 chips with heatsinks. I also have fan directed to the card.
Computer is Fujitsu-Siemens SCENIC E620, 2.66GHz celeronD, 1GB ram
System load is always below 0.3

I have ZoneMinder 1.24.2. I tried under OpenSuSE 11.3, and Slackware 13.1 same problem over and over again.

The problem is that one monitor keep dying. On OpenSuSE it was /dev/video3, and here on slackware is /dev/video2

It sometimes works 8 hours, sometimes die after half a hour. In log file zmdc.log ony says:

zmdc[8128].ERR ['zmc -d /dev/video2' exited abnormally, exit status 255]

zmwatch sometimes bring monitor up again, sometimes don't. The only solution is to restart ZoneMinder.

I have turned on debug logging, but found nothing. How to post the logs, because they are huge.

Code: Select all

# cat /etc/sysctl.conf
kernel.shmall = 354217728
kernel.shmmax = 354217728

Code: Select all

# cat /etc/modprobe.d/dvr.conf
alias char-major-81 saa7134
options saa7134 card=33,33,33,33

Please help!
