Date: Mon, 1 Jan 2001 11:04:58 -0700 Correction, it was actually kern_clock.c I modifed to prevent processes from being killed off. /usr/src/sys/kern >diff kern_clock.c kern_clock.c.orig 224,225c224 < printf("attempted to send SIGPROF to pid %d\n",p->p_pid) ; < /*psignal(p, SIGPROF); */ --- > psignal(p, SIGPROF); After making this change about a week later the following hits was observed in the syslog /var/log/syslog.log:Dec 30 09:49:15 firewall /kernel: attempted to send SIGPROF to pid 55305 /var/log/syslog.log:Dec 30 22:43:25 firewall /kernel: attempted to send SIGPROF to pid 64583 /var/log/syslog.log:Dec 31 09:33:28 firewall /kernel: attempted to send SIGPROF to pid 50306 Like I mentioned I have seen this bug on at least 4 different freebsd machines. There must be other people also having this problem and just not knowing why they have processes disappearing. It is very intermittent, in my case it took over a week and then I got these 3 hits.
