Description luna 2024-03-15 15:34:11 UTC 
SUMMARY

I have a mailbox with ~90k messages that, while rather slow, still worked under Plasma 5. Since upgrading to Plasma 6, when I try to reply to a message for that account (in *any* mailbox, not just the large one), kmail uses 100% CPU and seems to consume all memory on the system--when I last observed this, I let it go to 25 GB RES before closing it. I did not have this problem with Plasma 5.

STEPS TO REPRODUCE
1. Have or create a large mailbox, maybe 50k messages will suffice
2. Try to reply to a message in the account, in any mailbox, using either menu button or keybinding
3. Observe the application become unresponsive, using 100% CPU and eventually 100% memory

OBSERVED RESULT
Kmail uses all CPU and memory

EXPECTED RESULT
The compose window opens for the message reply

Yeah, you're right. This is definitely a dupe. Sorry for the noise, bugzilla's search is not great. :(
