Have experienced today strange issue with my fresh RELENG_7 ( =20 sources from yesterday April 13, userland and kernel in sync ) - =20 sometimes some processes stop running without any visible reason. Have =20 seen it twice today during KDE compilation - make process just waiting =20 for something while nothing else compiles or some other way prevents =20 this process from running ( no SIGSTOP performed, no Ctrl-S performed =20 on console). Well it possible related to ( or triggered by ) new ports =20 compilation feature for SMP machines ( most of KDE port marked as =20 MAKE_JOBS_SAFE=3Dyes ) but anyway this stuck process behavior is =20 strange. kill -SIGCONT not helps, but it killable ( Ctrl-C helps at =20 least ) Well some info related to this process: procstat -t 63472 output: PID TID COMM TDNAME CPU PRI STATE WCHAN 63472 100059 make - 1 92 sleep wait procstat -kk 63472 output: PID TID COMM TDNAME KSTACK 63472 100059 make - mi_switch+0x2c8 =20 sleepq_switch+0xd9 sleepq_catch_signals+0x239 sleepq_wait_sig+0x14 =20 _sleep+0x307 kern_wait+0xa36 wait4+0x3b syscall+0x2b3 =20 Xint0x80_syscall+0x20 Some related sysctls output: kern.smp.cpus: 2 kern.smp.disabled: 0 kern.smp.active: 1 uname -msr output: FreeBSD 7.2-PRERELEASE i386
