ENOURMOUS RAM USAGE 21GB MacOS Tahoe

[robert.jonas]

Hi.
Do someone experience this ridicilous amount of RAM memory usage? I have open only 8 emails and main window.

eM Client 10.4.4867 (a1d5549)

Yes, that can happen if you close and reopen eM Client without really ending it.
Every reopen adds ca. 0,3 GB of memory consumption.

ENOURMOUS RAM USAGE 21GB MacOS Tahoe

eM Client 10.4.4867

That’s very unusual for eM Client to use that sort of high ram usage if your mail is all fully synced and you only have one eM Client instance open.

I personally don’t experience that high ram issue with Tahoe OS 26.3 or 26.4 with an M2 Pro Mac. Mine is currently averaging around 450MB with 4 IMAP accounts open or minimized.

So “if you have only just setup eM Client” and just added your accounts, it could be eg: synching serious amounts of server mail and other data to your client causing that unusual amount of ram usage “depending on how many accounts you have” and “the size of each server mail account”.

Also if you have eg: multiple eM Client windows open at the same time all synching mail etc that can also use up alot more ram than normal.

So first thing “click the dropdown on the right of Refresh and click “Show Operations” and see if eM Client is still synching anything. If it is “then wait till that’s all completely finished” and then see if the ram usage comes down after leaving it open in the background or leaving it minimised for a while.

If your mail accounts are already fully synced and only one instance open and nothing showing in Show Operations, then try “close / exit” eM Client” and “shutdown and reboot” as could be possibly an OS glitch showing incorrect amount of ram usage.

If rebooting still shows the same high ram usage, then update “what Mac OS version you are running”, and also “what Mac hardware you have”.

Have you tried to close eM Client via the red button, then reopen it and do that a couple of times, observing the memory consumption with the Activity Monitor?

I’d be very interested in your results compared to mine, as I described it in:

Some observations on memory consumption on macOS Tahoe

Running on Mac Studio, M4 Max, 36GB Ram eM Client 10.3.2622, macOS Tahoe Version 26.0 Beta (25A5316i) Fresh start of eM Client (eMC) yields a memory consumption of ca. 720 MB Now, when i close eMC via the red button (x) it goes into sort of idle. It’s not sleeping, it still syncs after the configured sync-interval. All good, the same as on macOS Sequoia. But, after a while, any subsequent reopening of eMC then seems to add ca. 300 MB memory consumption to the process. so it goes: 750 MB, c…

btw This hasn’t changed with my current configuration:
eM Client 10.4.4924, macOS Tahoe 26.4

Yes if i keep clicking the Red dot to close the window and then reopen the window after about 30-40+ times the application usage climbed up to around 3.00GB . Never tried that before.

I normally never click the red dot and just minimize the app so never struck that before.

So yes there seems to be some issue with the app “where reopening the app window if its not completely closed first” adds memory usage. even using eM Client V10.4.4924 / OS 26.4

Thanks for taking the time to experiment.
Anyway, it’s not a big deal for me, I switched to minimizing eM Client.
When I posted this, I just wanted the developers to know.

I think it’s important to note that MaOS manages RAM completely differently than Windows. MacOS believes unused RAM is wasted RAM. Therefore it preloads processes and caches files that MAY be used in order to speed up the system. If that RAM is required by another process it will release it to that process.

The high RAM usage you may be seeing could actually be due to the OS, not eMClient itself

[cyberzork]

Testing my same 4 IMAP accounts fully cached in eg: Mac Mail to compare, after closing via the Red dot and re-opening Mac Mail around 30-40+ times the memory usage only climbed to aprox 30MB more to around 180MB, compared to eM Client that climbed from 450MB to 3.00GB doing the same test, so i agree with @ttf this appears to be an eM Client issue and not an OS issue.

I’m not sure comparing Mac mail to em Client is a good comparison. Yes, they both handle mail but eM Client has a much more robust feature set. I still believe it’s the OS. But I’m hardly an expert on the subject.

…I still believe it’s the OS…

I wouldn’t exclude it, however, I think it’s unlikely.
A “memory leak” like that would show up tens of thousands of times during a normal workday an a machine - reactivating processes, forking new ones etc., all those are very common and basic “bread and butter”-activities of any OS.
I tested a few apps like Word, Excel, PDF Expert - none of those shows that memory eating.
