zoneminder 1.22.3 no video shared memory error

rrk · Post by **rrk** » Sun Jun 10, 2007 11:32 pm

i seem to be missing something for shared memory allocation
the log error in zmwatch.log is
[Can't get shared memory id '7a6d2003', 3: No such file or directory]
so zmdc is restarting
['zmc -d /dev/video' starting at 07/06/10 18:14:02, pid = 3711]
should there be a device number like /dev/video0 instead of just /dev/video?
when i look at shmall and shmmax that is a little strange also
cat /proc/sys/kernel/shmall 2097152
cat /proc/sys/kernel/shmmax 33554432
i thought shmall was the max that could be allocated in 1 chunk
why is it smaller than shmmax and why is it so small?

any help would be appreciated
rob

As zmc is capturing images, I'd start looking into apache to see why you can't get a stream.
Check the apache error log, and see what path for zms is being passed to the client.

got it thanks cordel -- it was using nph-zms instead of zms -- what is the
difference between zms and nph-zms ?
switched to zms and everything appears to work

The binaries are exactly the same except for the file name. Apache interprets the nph as No Parse Headers so it does not parse the headers.
