Are you running KDE?


Yes! It is v3.3.

What does "hostname" and "xauth list" say?


silvermedia at dhcppc2:~ > hostname
dhcppc2
silvermedia at dhcppc2:~ > xauth list
[*]
192.168.3.70:0  MIT-MAGIC-COOKIE-1  30a663ff2ff8b92463098edb63d53518
dhcppc2/unix:0  MIT-MAGIC-COOKIE-1  30a663ff2ff8b92463098edb63d53518
[**]

Here [*] means that I have to wait about 4 seconds and [**] means that I
have to wait until eternity (only CTRL-C stops this request and the
~/.Xauthority file is locked until pressing CTRL-C, so I am unable to start
another "xauth list" parallel).

In fact I have a quite slow DHCP setting configured. If I change it (and
modify /etc/resolv.conf) then I get

silvermedia at dhcppc2:~ > xauth list
192.168.3.70:0  MIT-MAGIC-COOKIE-1  30a663ff2ff8b92463098edb63d53518
dhcppc2/unix:0  MIT-MAGIC-COOKIE-1  30a663ff2ff8b92463098edb63d53518
192.168.3.70:0  XDM-AUTHORIZATION-1  3b7848b74d7625c4006c421082f99d8c
dhcppc2/unix:0  XDM-AUTHORIZATION-1  3b7848b74d7625c4006c421082f99d8c
linux/unix:0  MIT-MAGIC-COOKIE-1  34be9ae04f8a07e46ae0e2b670047610
linux/unix:0  XDM-AUTHORIZATION-1  961c7e5b6c817e74009743c89cd6980a
dhcppc1/unix:11  MIT-MAGIC-COOKIE-1  9d48064b336a4e01a3ba23618e3a77b2
dhcppc1/unix:10  MIT-MAGIC-COOKIE-1  a8d4d112344707450c254b594a08d19d
dhcppc2/unix:10  MIT-MAGIC-COOKIE-1  139288cea5ad6d742a0eb323a1fb7475

And it comes immediately and exits normally.

Some more info: We use this complex application as an advertisement system.
The machine runs continuously, however there is a reboot every day early in
the morning. First I didn't want to do any rebooting because I trusted the
system it does not need rebooting. First we thought that any of the
application parts may be a memory hog but now it is likely that some
internet misconfiguration can be the issue.

Another thing, that as far as I can remember, when the crash occured, a
"kdontchangethehostname" process also run continously. Now I don't see any
copy of such a process (now I rebooted the machine of course).

TIA, Zoltan
