Hello, i have zoneminder 1.23.3 in debian Lenny. installed following this tutorial:

http://www.thinkdebian.org/archives/50

I changed the /etc/sysctl.conf value:

####################################
# Memory Allocation for ZoneMinder #
####################################
kernel.shmall = 536870912
kernel.shmmax = 536870912

But i still get a lot of randomly black outs, this is the output of the /var/log/syslog | grep ERR

Aug 14 11:36:49 monitoreo zmc_m1[15735]: ERR [Invalid JPEG file structure: two SOI markers]

1. Panasonic BL-C101


Maybe someone can point me to some place or give me some new ideas, i have already look for it in google...

Thanks!
