I'm running radius server which in turn serves user requests by running application. The application connects to another host (mysql server) and gets data and do some calculations and return results. Application runs fine, but from time to time it hangs and I can see it using ps -ax command. So when application hangs radius can not serve user requests any more waiting the application to finish. Before updating from FreeBSD-5.2-STABLE to RELENG_6 it was working fine and I didn't observe such problem for 2 years. Since upgrading to RELENG_6 a couple of months ago this problem appeared. While application was hanging, I can log into the system. I can log into another mysql host which is the exactly same machine with more RAM. I checked mysql server's processlist by running 'mysql show processlist' and there wasn't any process running and locking the tables. I'm using mysql client/server-4.0.27 from ports. So do I have interrupt storms here and it is something related to bge? What else should I check when application hangs again? Here is dmesg, vmstat, ps outputs: http://www.mnbsd.org/ftp/rad_hang.txt thanks, Ganbold
