Im new to ZM and relatively new to Linux so I hope you'll forgive me if I'm asking a stupid question, I have installed ZM1.32.3 using this guide:
https://wiki.zoneminder.com/Debian_9_64 ... e_Easy_Way
I am running a fresh install of Debian 9 and have now got everything working quite well after a few teething issues such as missing Number::Bytes::Human perl module and missing .htaccess files causing url rewrites not working for the API. That all now works great with zmNinja.
I only seem to have one issue...and not sure whether it's completely normal or if there's something amiss.
I have 8 H264 camera feeds, they are all set to fixed 10 or 15fps with variable bitrate, at varying resolutions from 1MP up to 4MP. They are all on mocord and are recording using ffmpeg with the H264 passthrough option. I have removed the max fps and max alarm fps setting and this solved an issue with smudging. Now the live images are great and so are the recordings. The only problem is that a few times a day I get chunks of the following in the log file...
It seems to happen at random usually about five or six times a day and seems to affect a couple of random cameras at a time. When I view the playback I just get a few messed up frames at the time of the errors, occasionally losing a few seconds of video. It's really bugging me and would love to know if this is a common thing...is it caused by the cameras missing frames or perhaps a problem with my setup?2019-02-25 16:52:24zmc_m98458WARUnable to receive frame 326686: Resource temporarily unavailable, continuingzm_ffmpeg_camera.cpp900

My system load doesn't go above 4%, and shared memory sits at around 25% used. Only been running a few days so HDD storage only at 3% full so far. Network load is only about 2.5Mbps going through Cisco 3560 12 port POE switches with cameras on a dedicated vlan. No bottlenecks on IP network.
I hope I've included enough information for someone to kindly offer me some advice.
Thanks
David
