hey, I'm noticing that if I run the unix.c program from <A NAME="-1"></A>[1] in a tight loop on 2.6.28-rc5, I get frequent soft lockups. Eventually, the OOM killer kicks in and starts taking out other processes. I've posted a console log here: http://free.linux.hp.com/~dannf/unix-soft-lockups.log <A NAME="1"></A>[1] http://marc.info/?l=linux-netdev&m=122593044330973&w=2 -- dann frazier -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html <b>[prev in list] [next in list] [<font color="#c0c0c0">prev in thread</font>] [<font color="#c0c0c0">next in thread</font>] </b> </pre> </pre><br><center> Configure | About | News | Donate | Add a list | Sponsors: 10East, KoreLogic, Terra-International, Chakpak.com </center> </body> </html>
