Running processes (state R) keep running smooth until they try to access any resource (ie. xmms keeps playing the current file but gets stuck when trying to open next one, top keeps running with full interactivity). Spawning new processes is impossible. I had top running over SSH and when I exited I managed to type 1 char then it hung up. A note is that sometimes the load is ~45% user ~55% system instead of ~55% user and ~45% system. There are always those values. I tried to reproduce by creating a while(1){} loop but it runs smooth. Any suggestions on methods to debug this? --=20 Christian Axelsson smiler@lanil.mine.nu --=-+Yd4GE0dZvuLdg4m6Uga Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQA/D0pAyqbmAWw8VdkRAnM8AKDcWK4i7whUD75yON0t9dC22rfhHwCgs0X0 0znl7oiIMCZxB74cPT1qRAc= =9dmI -----END PGP SIGNATURE----- --=-+Yd4GE0dZvuLdg4m6Uga-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
