HI everyone!

/var/log/zoneminder/web_php.log

03/04/20 14:18:42.317826 web_php[5350].ERR [192.168.5.14] [Socket /var/lib/zoneminder/sock/zms-417005s.sock does not exist. This file is created by zms, and since it does not exist, either zms did not run, or zms exited early.

hello v.mazurenko,

I have also seen this error recently as well. for a camera using "Remote" I have to use zmc -m 2 from a terminal and then it works.
Puppy Linux Tahr 6.0.5 ZM 1.35 zoneminder-master

I upgraded from 1.30.4 which had worked perfectly. I am testing with the set up so something was expected. I am tying to hammer out what is wrong exactly.

i found that process restarts every few minutes. Look at PID

apache 4284 1.6 0.8 518712 16324 ? S 08:29 0:00 /usr/bin/zmc -m 1

after few minutes:

apache 4319 5.0 0.8 518712 16324 ? S 08:29 0:00 /usr/bin/zmc -m 1


Also noticed :

apache 4979 0.3 0.8 518712 16328 ? S 08:38 0:00 /usr/bin/zmc -m 1
apache 4997 9.0 0.6 277396 11604 ? R 08:38 0:00 /usr/bin/perl -wT /usr/bin/zmdc.pl restart zmc -m 1
