Hi,

This is my first post on the forum, I am trying to set up a zoneminder with 3 Axis IP cameras, but I am having some problems.

The data of the server where i run zoneminder is:

CPU Core Duo
1 GB RAM
Linux distro: Ubuntu 11.04 server
ZoneMinder 1.24.4

sysctl.conf:
kernel.shmmax=5637880627
kernel.shmall=1529373

The cameras are configured to send a TCP message (1|on+1|5|Alarm|Alarm|Alarm) to zoneminder in case of alarm, but the script zmtrigger.pl crash randomly with this message:

variable is not a string at /usr/share/perl5/ZoneMinder/Memory/Mapped.pm line 109.

Thanks for any reply

I am also experiencing this. Using CentOS 5.7 x64, perl 5.8.8.

I have several Axis cameras, but only one is currently set to send event notifications to zmtrigger via TCP. zmtrigger works for a few minutes, but always crashes after that. I have not been able to pin it to a certain event.

I have traced the error to a call to zmMemInvalidate in zmtrigger.pl, at line 290. Here is the %monitors hash dumped just before the foreach loop that calls zmMemInvalidate:
