Bug#494691: kmail: huge memory usage when copying/uploading mails
Package: kmail
Version: 4:3.5.9-5
Severity: normal
*** Please type your report below this line ***
Hi. Kmail is fast when moving mails between (local) folders, but when
copying mails it takes a long time, and uses a lot of memory. Also the
user interface freezes while the copy is taking places.
FYI, I did copies by selecting all mails in the mail list pane (Ctrl+A),
right-click, Copy To.
Another very bad case, is when you have a cachedimap account, and copy
files from a local folder to it. The (local) copying is slow, but what
is far worse, is when you tell Kmail to synchronize. On my PC, the
memory usage grew up until 1420m VIRT (according to top), and then froze
and forced me to reboot my workstation.
This was with about 4000 mails, with 230M of file data. Also, the IMAP
backend is Zimbra 5.
My requests are:
1) Don't freeze kmail gui while copying files between local folders
2) Please show the progress of local mail copies.
3) Same as above when moving between local folders.
4) Don't use up a lot of memory while copying between local folders
5) Don't use excessive memory when synchronizing cachedimap (uploading
4000 mails with 230 MB data from local cache to IMAP shouldn't use 1.4 GB).
David.
