Two days ago, I built my first dedicated ZM box. Worked fine for 24 hours, but after recompiling the kernel and rebooting, I get this...
/var/log/messages
Code: Select all
Sep 29 01:29:19 cctv bttv0: reset, reinitialize
Sep 29 01:29:19 cctv bttv0: PLL: 28636363 => 35468950 . ok
Sep 29 01:29:19 cctv zmc_d0[6142]: ERR [Sync failure for frame 0 buffer 1(1): In

valid argument]
Sep 29 01:29:19 cctv zmc_d0[6142]: ERR [Sync failure for frame 0 buffer 4(1): In
valid argument]
(END)
I went back to my original kernel (I had a backup of bzImage), but it's just the same.
kernel.shmall = 134217728
kernel.shmmax = 134217728
There is nothing in the ZM log files that looks bad, except for the watchdog kicking in. The bttv driver loads ok (cheap single-chip 4-port ebay card).

I dont have another card. I was going to get a better one at some stage... guess that will have to be sooner than I had expected.
Thanks,
Stuart.

It's a £15 UCC4 single chip thing I got off e-bay ages ago.
I have rebooted a zillion times. Pulled the power. Moved PCI slots. I put everything back as it was (as far as I know), and still it fails to work. I guess I could zap the mysql database settings, and start again, just in case I did something wrong while it was working.

if mysql was out you wouldnt be getting the card errors you posted at first. It might cause you not to be able to connect to the console and may not allow recording but capture would function (even if you couldnt see it)
BTW the card that failed on me was an ebay one too

I wasn't so much thinking mysql was bad... just that I may have changed a setting somewhere while it was working, and caused it to fail after the boot. That said, I didn't change much, and I have checked it all.
It's just that in the /messages log it says "Invalid argument", making me wonder if its a configuration problem?

i assume you have checked the cam is ok or are there multiple cams that have died?

Just tried swapping the cameras again. Same.
Just noticed this pop up in the zmwatch log:
Code: Select all

I have completely rebuilt the database, and reconfigured my camera, but the same old errors persist.
I still get
Code: Select all
Can't execute: MySQL server has gone away at /usr/local/bin/zmwatch.pl line 121.

I'm wondering if thats just a consequence of some other failure.. either way, mysql seems fine. I can access the tables ok.
