Re: Zoneminder processes being killed by OOM and OOMD on Fedora

I installed an older version of ZM (1.34.26-1) on Fedora 34. This was installed without on disk swap, so with only compressed swap in RAM. This older version of ZM was unavailable on Fedora 35, otherwise I would have gone with the newer Fedora. The memory usage has been low and stable over time - me...

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Turning off Save JPGs does disable live view, which is a dealbreaker. I don't know what to do at this point, perhaps I'll try a different distribution perhaps CentOS or Ubuntu. Or perhaps install an older version of ZoneMinder (1.34).

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Also, for some reason I could no longer see any live views (e.g. montage or camera view). I need to investigate if disabling JPEGs caused this. I will add that if ZM crashes after 3 days, I can work around this with nightly reboots. Still probably needs some investigation by the devs at some point t...

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Try disable saving JPEGs if you haven't already. ZM got killed by OOM after 3 days (?) after disabling JPEGs. I will note that I was running with OOMD off (see oomd.conf in my first post). Here are some "top"s over time. I only got 2 days worth. ZM was killed about 12 hours after the last...

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Just to add some more information, here are the settings for one of the cameras. There appears to be a limit, so will add more settings in another post.

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Thanks. I will try that and report back. "Save JPEGs" was set to "Analysis Images Only (if available)".

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Not solved. ZM keeps getting killed. It looks like ZM is hanging onto too much memory. If there's anything else I can post here that can be of help, let me know. Here's a "top" of the system after running for a while:

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Adjusting the reserve ratio did not work. I kept halving the numbers until I reached the minimum. In other words, I tried these values for vm.lowmem_reserve_ratio: 128 128 32 64 64 32 32 32 32 16 16 32 8 8 32 4 4 32 2 2 32 1 1 32 However, after each adjustment OOM always kicked in and killed ZM. I t...

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Spoke too soon... Zoneminder has been killed. I will keep on playing with the values for the reserve ratio and see what happens. Here's the service log, in case anyone is interested: Dec 30 16:53:03 zmstats[868]: INF [Stats Daemon exiting] Dec 30 16:53:03 zmdc[805]: INF ['zmc -m 1' exited normally] ...

Re: Zoneminder processes being killed by OOM and OOMD on Fedora

Forgot to mention Zoneminder is running under nginx, and not Apache. It's probably not relevant, but thought I'd include this.

Zoneminder processes being killed by OOM and OOMD on Fedora

Hello, I recently installed Zoneminder on Fedora. I was having some issues with Zoneminder being killed by the system OOMD and OOM processes. I changed my settings for both and so far all seems ok. I'm hoping that what I post here can help someone. Or perhaps the powers that be can suggest better se...
