message view spawning multiple processes that does not quit

Reported by moiraine | September 8th, 2020 @ 08:26 PM

On build 1.13.2 (5719), using the new message view, after viewing a couple of messages, mailmate will spawn multiple webview processes that does not quit (e.g. seen by searching for mailmate in the activity monitor, screenshot below); in terminal, the corresponding pid for the "about:" processes in the attached screenshot is

2541 ??         0:00.34 /System/Library/Frameworks/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.WebContent.xpc/Contents/MacOS/com.apple.WebKit.WebContent

Also, running on macos big sur beta (20A5374i), not sure if this applies to non-beta systems.

    I'm aware of this issue. It's actually a side-effect of an intentional feature (a cache of recently displayed messages), but the memory usage is naturally unacceptable. I'll have to figure out a different approach.

    This seems to have gotten worse either in the beta releases or with macOS 12. Even with 64GB of memory, this eventually causes system stability issues after a day or two. MailMate had around 1800 processes using 17GB of memory, and surprisingly it was affecting Safari as well.

    Are there any workarounds for this?

    Which revision are you using now? Hold down the command key when clicking “Check Now” in the Software Update preferences window. As far as I know, this should be much better now.
