           Summary: opening lan:/ with "many" (>500) hosts in the LAN ->
                    memory hole
           Product: lanbrowsing
...
        ReportedBy: bugs.kde.org at jensbenecke.de


Version:            (using KDE 3.1.9)

Hi,

when I do 'telnet localhost 7741' (-> connect to lisa) I get a list of 530
 hosts (this is a university). when I open "lan:/" in Konqueror's sidebar
 (the "Network Browser" icon, one of the "konqueror --preload" tasks starts
 eating memory like wild. On my 128MB machine, this causes the machine to
 start swapping wildly and not respond for about 10 seconds.

When it is finished, the task suddenly consumes about 60-100MB (!!) of RAM.
 Just for the share list. I think this is too much. :-)

When I close the Konqueror window, this memory is freed, however. (not when I
 collapse the "LAN browser" tree, however)

So I think kio_lan needs to optimize memory useage. :)


Thank you!

I asked Jens for more information:

So it seems konqy eats the memory.
Unfortunately I can't reproduce it here, my network consists of 3 boxes.

Any ideas how to deug this ?

Bye
