#2646 reproduced

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 can confirm the existence of many 'about:' processes, also on macOS Catalina 10.15.7 using MailMate 5721. For me it's >100 of those processes, each of which using 80-100MB of memory.

    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.

    Besides the 'about:' processes mentioned above, I've also noticed multiple MTLCompilerService processes that are also related to MailMate. They're putting some real CPU load on my system and I usually need to close MailMate then, to be able to use my Mac normally again.

    In contrast to the 'about:' processes, they don't appear with every message read, but more seldomly — it seems related to HTML mails with images, but I'm not 100% sure.

    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?
