[kdepim-users] Why is KMail so memory-hungry?

[Peter]

Hi Bill,

Yes, I have found the same problem. If my computer is very slow, in any app, I 
look at system monitor, and it is always KMail, either chewing up CPU or 
memory.

I use Ubuntu 9.04

It often crashes, especially after I do a search, and then looses all current 
flags (mail read, fowarded,etc).  Not real impressed with the memory management 
side of things.
