The process is called "konqueror --preload".

Here's a valgrind output if that helps. However, this doesn't show the
actual konq process eating the RAM (it uses one of the preloaded
processes). I don't know how to attach valgrind to a running process,
but I do have an strace of a running konqueror eating about 60MB of RAM
because of opening lan:/. It's about 1.2MB however.. I can also send you
a stripped version (without thousands of read() / write() calls) if you
want.

Hi, this bug hasn't been updated for a year. I don't have access to a machine with the LAN ioslave installed right now, can anybody still confirm this? Thanks! Hi, I cannot reproduce this with 3.3.2. This might be because we only have about 300 machines in the current LAN (in contrast to 530 before)... but I doubt that. Closing, for the time being (at least until I can reproduce). |
