Bug#750479: kde-runtime or something related leaks file descriptors
Package: kde-runtime
Version: 4:4.13.1-1
Severity: normal
Dear Maintainer,
this report is a bit vague, as about root cause for the problem I have
no clue. I'm reporting this against KDE but problem might be in any
linked component or just incompatibility with some libraries installed.
First, for producing the problem I do the following:
1) have kdm as display manager
2) login, using kde and plasma-desktop and everything, normal kde
3) open firefox, put random youtube-film on display
4) simultaneously open lowriter and random ms-word dokument
5) simultaneously open evolution mail and check mail
6) simultaneously open chromium for browsing of random interwebs
after ~4-5 minutes of use, programs start complaining about max number of
open files in system having been exceeded, after which
nothing works, I don't even have an entry from /var/log/messages as it
can't be written any more. "dmesg" can be used to display the cause for
programs crashing, and from command-line they just report ENFILE - 23.
Limits are high,
* soft nofile 1000000
* hard nofile 1000000
and I did not manage to spot the culprit by inspecting /proc/*/fd but
this happens suddenly and the sometimes recovers a bit after all
programs are closed, at least to the point that xterm may be opened. But
not always.
The reason for reporting this against kde is that if I repeat the above
steps using gdm+gnome combo, the system works just as it should, now
for 5 hours straight.
It seems to be that the problem appeared after monday morning update,

so most likely one or more of the above are to blame but as said, I
have no clue. I can still reliably re-produce the problem.
