Hi,
Sorry my english!!!
I decided compiled ZoneMinder 1.22.1. Let's all fine.
But now when I run the monitor I get the following errors.
I use Creative Webcam Pro

(/var/log/messages)

would seem to imply you haven't set a device for your monitor. Can you confirm whether this is true or not?

No, the device is configured.
It stows observing that when dumb the resolution the error modifies.

If you do an 'ipcs -m' what do you get?

This indicates that you have a ZM shared memory segment owned by root. Unless you have run the process manually as root, or have specified root as your web user this should not be possible. You should delete this segment with ipcrm and then try and restart ZM.

facoliveira · Post by **facoliveira** » Thu Apr 27, 2006 11:30 pm

I delete this segment: ipcrm -m <id>
And restart ZM.

The first error was after command: /etc/rc.d/rc.zm restart

I`ve updated the default shared memory limit for SHMMAX is 101 MB and for SHMALL is 101 MB.
But i receive the folowing erros:
In 176x144 and 320x240 - 5fps

Code: Select all

*** glibc detected *** malloc(): memory corruption: 0x0daff980 ***

In strace zmc -d /dev/video0 is exactly error.

In /var/log/messages is the same error.

In /var/log/syslog

Code: Select all

zmdc[7769]: WAR [Can't find process with command of 'zma -m 1']

And others logs is the same.
