I experience a problem where vpnc can not exit cleanly and gets stuck. pstree shows this chain: |-+= 31375 root vpnc | \-+- 13412 root /bin/sh /usr/local/sbin/vpnc-script-custom | \--- 13446 root ifconfig tun0 destroy $ procstat -k 13446 PID TID COMM TDNAME KSTACK 13446 102739 ifconfig - mi_switch sleepq_switch sleepq_wait _cv_wait_unlock tun_destroy tun_clone_destroy ifc_simple_destroy if_clone_destroyif if_clone_destroy ifioctl soo_ioctl kern_ioctl sys_ioctl amd64_syscall Xfast_syscall My system is FreeBSD 10.0-CURRENT amd64 r236503. I think that this started happening recently but I am not sure exactly when. Maybe after recent vpnc-scripts update or maybe after base system + kernel update. Any help/hint is very welcome. Thank you! -- Andriy Gapon
