ZoneMinder Forums

Hey Everyone,

I just set up a zoneminder 1.29 on a raspberry pi running "jessie"

I'm able to add my cameras and i can see the streams from the cameras just fine. However, if i have the montage view up, every so often a camera will freeze and i'll see the following in logs:

Jan 29 22:58:13 raspberrypi web_php[1538]: ERR [socket_sendto( /var/run/zm/zms-734563s.sock ) failed: No such file or directory]

if i LS that directory, sure enough the file is missing:
srwxr-xr-x 1 www-data www-data 0 Jan 29 22:53 zmdc.sock
-rw-r--r-- 1 www-data www-data 4 Jan 29 22:53 zm.pid
-rw------- 1 www-data www-data 0 Jan 29 22:59 zms-794677.lock
srwxr-xr-x 1 www-data www-data 0 Jan 29 22:59 zms-794677s.sock

If i reload montage, both streams come back and LS will show that as well:

pi@raspberrypi:/var/run/zm $ ls -l
total 4
srwxr-xr-x 1 www-data www-data 0 Jan 29 22:53 zmdc.sock
-rw-r--r-- 1 www-data www-data 4 Jan 29 22:53 zm.pid
-rw------- 1 www-data www-data 0 Jan 29 23:05 zms-134186.lock

srwxr-xr-x 1 www-data www-data 0 Jan 29 23:05 zms-601469s.sock

now i know from my googling, that this error is relatively common on new installs where the ZMS path is set wrong. I don't believe this to be the case here since my streams actually do work, they just intermittently fail.

Any insight would be greatly appreciated.

Socket Sendto errors are not fatal and likely the result of the browser. I have several PC's set to view montage in one building and was seeing a lot of these errors. PC's using Firefox. I found an add on that refreshes the browser every 5 minutes and the errors (almost) stopped!

Another option for refreshing is xdotool. I've documented that here:

I use surf (for <6 cameras only), but any browser could be used.

There are some addons for FF, but may require esr, possibly. (52)

Okay the browser refresh would certainly be a good workaround. I was wondering if that stream disappearing could also be a result of network connectivity from my cameras. They're WiFi and they drop quite a bit of traffic.

I suppose I can do a little more testing to rule that in or out.

Thanks again
