Any ideas what could be causing this or how to correct?

This is only happening if I'm watching a feed live. For example, with the Montage view up or the Watch view up.

This problem started with "nightly-1224" on July 12th with commit bdb0768dfe52034d1e6926fe6c897e6b9b6283b3
and occurs in every nightly after that.

Is this with zmNinja? It has been known to ignore the StreamImageReplayBuffer setting.

You may want to move that path to a tmpfs for performance...

Will do some testing. It seems to be trying multiple times to write that jpeg, but the #'s should be increasing... weird.

Posted: **Tue Jul 25, 2023 8:14 pm**

zmNinja is not installed. Where should I change the directory that it's writing to?

Look into ZM_PATH_SWAP in conf files in /etc/zm/conf.d.

The latest build should fix the Error.

Posted: **Wed Jul 26, 2023 12:28 pm**

Thanks. Yes. It's fixed in last night's build "nightly-1236".

In the docker container: zoneminder-containers/zoneminder-base, I found the ZM_PATH_SWAP variable in the following file:

Code: Select all

/zoneminder/defaultconfig/conf.d/01-system-paths.conf/01-system-paths.conf

Checking for tmpfs usage:

Code: Select all

I think I'll let the maintainers of this container handle moving this to a tmpfs as I'm not sure how to automate this.

Thanks again
