even small applications need lots of time for loading


Hi there.

I am currently concerned about a strange behavior of my Gentoo system.
Just a few specs: Dual PIII-1.4GHz, 4GB RAM, Kernel 2.6.24

Following problem i noticed: after a long uptime (>31days) my system is dramatically slow when loading any application. With "slow" I mean 4minutes(!!!) from typing xterm until a new xterm window pops up. Once the application is started, everythings runs at normal speed and there's nothing to concern about anymore. Anyway, the delay before a program starts is increasing from day to day. The machine is a 24/7 server and I can't afford to reboot it every once a while.

I used strace to figure out what makes my machine hanging for such a long time before something new is happening.

You can analyze the log here: http://nopaste.ch/48902c55f1bc6dd.html

The execution stops at line 269 and is waiting 4minutes until running on.

Anyone an idea?
Thanks in advance
Michael

Of course I did.
top says: everything fine. Approx. 99% idle for each CPU, no system oder wait load while starting any app.

Interesting thing: when starting applications out of a ssh-connection everything runs absolutely normal: *snip* application up and running.

Seems to me the problem described just occurs when starting an application out of a X-Window.

Edit: Aaaah I think I got something very interesting: Startet an app out of X and following error message comes up:
Code:
Warning: Tried to connect to session manager, Could not open network socket
Well, that explains at least why execution stops at line 269 (see code link above).

Any suggestions?

Thank you so much for posting the log elsewhere -- it makes it so much easier to follow your post.
