It does not react to a HUP signal, and neither to KILL. The /dev/da0 device is operational and the remote disk remains normally accessible, regardless of how I try to (unsuccessfully) shutdown the iscontrol process. The ps reports the state of the process as "Ds", not doing anything. A ktrace does not show any reaction to a received signal. A restart seems to be necessary to break the iSCSI session. Using FreeBSD 9.0-rc2, amd64, also tried with 9.0-PRERELEASE (csup tag=RELENG_9 as of today). This used to work normally as documented on the same host with the same iscsi.conf config file before upgrading from 8.2 to 9.0. Anybody else experiencing this problem? Suggestions welcome. Mark
