Package: kmail
Version: 4:26.04.3-2
Severity: normal
Here is an example of the typical output of "ps auxf" showing significant
amounts of RAM used by QtWebEngineProcess spawned by kmail.

Here are examples of free -m run before and after restarting kmail. It seems
that
most of my swap space is used by the QtWebEngineProcess children of kmail.

Running kmail for 12 days isn't really a lot for a desktop or laptop system.
I think that if we can't make QtWebEngineProcess use less RAM then we should
have kmail periodically restart it. Having kmail restart it is probably a lot
easier than fixing bugs in it.
