Exit status 255

Hi,
I've installed 1.20.0, but I get a broken image when I try to view a monitor. This error seems to occur a bit on the forums, but I couldnt find a successful resolution.

/tmp/zmdc.log gives this repeated:

Code: Select all

Can't find process with command of 'zma -m 1

There are no other /tmp/zm*.log files.


/var/log/messages gives this over and over:

Code: Select all

My capture card is a Conexant BT878A, using the Linux 2.6.7 video4linux/bttv drivers.

The kernel seems to be detecting the card and assigning it /dev/vdi0 and /dev/video0. I linked /dev/vdi0 to /dev/video4 so I could try zoneminder with that as the device, with no luck.

Any assistance would be greatly appreciated.

Thanks in advance,
Patrick

Please include what your distribution is, otherwise it's hard to tell what goes where logs-wise. On some distros errors actually go to a different file in /var/logs/ so it's probably worth grepping for ERR in all files in tat directory.

Distro is Slackware 10.

aha. Grepping for "ERR" gives a heap of errors in syslog:

Firstly,

Code: Select all

syslog:Jan 23 16:45:10 server zmc_d0[15120]: ERR [Failed to open video device /dev/video0: No such device]

appears about 7 times, probably because I hadnt inserted the module correctly at that point.

Then we get a heap of

Code: Select all

syslog:Jan 23 16:46:38 server zmu[15197]: ERR [Can't shmget, probably not enough shared memory space free: Invalid ar
gument]

which seem to stop after a while; I had a look at the README and tried dropping the buffer to see if it made a difference.

Then they stop, and we get this:

Code: Select all

syslog:Jan 23 16:53:45 server zmc_d4[15396]: ERR [Could not mmap video: Invalid argument]

then this:

Code: Select all

syslog:Jan 23 16:53:50 server zmu[15411]: ERR [Shared memory not initialised by capture daemon]

then some more 'could not mmap video' then a few

Code: Select all

syslog:Jan 23 17:15:30 server zmc_d0[15617]: ERR [No monitors found]

then finally

Code: Select all

syslog:Jan 23 17:23:58 server zmc_d4[15643]: ERR [Could not mmap video: Invalid argument]
syslog:Jan 23 17:25:30 server zmc_d0[15646]: ERR [No monitors found]

alternating over and over again (roughly once every ten minutes) until the end of the output.

Hope that makes sense.
