I see this, too. And I have a calendar on webdav, too! This is KDE-3.5.4.

possible leak plug

Rolf,

Any chance you can apply the patch for kdepim/libkcal/icalformat.cpp
that I just attached to this bug report.

and test again with valgrind?

SVN commit 590304 by winterz:

greatly reduce memory leaking, according to valgrind.

I still experience this problem, although maybe to a lesser extent? Not sure
about that.

I am using KDE 3.5.7. I have had korgac running for about 24h and it grew from
19 MB RSS to 88 MB RSS. This seems pretty bad. Maybe some more valgrinding is
in order? :-)

Running KDE 3.5.8 on Debian testing, and korgac still leaks memory. My uptime
is now 5h, and korgac VmRSS size has doubled from 31 MByte to 63 MByte, when I
checked.

Valgrind logfile

Ok, I have run valgrind for maybe an hour or so on korgac. You find the log
attached. It shows that korgac still loses significant amounts of memory. In
this case, 10MB.
