In the log I have this: Aug 18 18:50:19 freenas ctld[2680]: 192.168.0.122: exiting due to timeout Aug 18 18:50:19 freenas ctld[2683]: 192.168.0.122: exiting due to timeout Aug 18 18:50:19 freenas ctld[2679]: 192.168.0.122: exiting due to timeout Aug 18 18:50:19 freenas ctld[2681]: 192.168.0.122: exiting due to timeout Aug 18 18:50:19 freenas ctld[2682]: 192.168.0.122: exiting due to timeout sonewconn: pcb 0xfffff80045e88ae0: Listen queue overflow: 193 already in qu= eue awaiting acceptance (1 occurrences) sonewconn: pcb 0xfffff80045e88ae0: Listen queue overflow: 193 already in qu= eue awaiting acceptance (322 occurrences) sonewconn: pcb 0xfffff80045e88ae0: Listen queue overflow: 193 already in qu= eue awaiting acceptance (340 occurrences) sonewconn: pcb 0xfffff80045e88ae0: Listen queue overflow: 193 already in qu= eue awaiting acceptance (340 occurrences) netstat -Lan reported the issue about the port 3260 (iscsi) It seems to happened while I try to rename a ZVOL (zfs rename ...) I tried to stop the iscsi service from the GUIwith no luck: /etc/rc.d/ctld stop did not produce any effect (process was stuck) I tried to kill the process manually: (2281 is for /usr/sbin/ctld)=20 kill -9 2481 kill -HUP 2481 kill -KILL 2481 kill -19 2481 but no luck. For a strange reason: /etc/rc.d/ctld stop returned: ctld not running? (check /var/run/ctld.pid). (the service was definitely running) ps aux | awk '$8=3D=3D"Z" {print $2}' returns nothing At the end, I rebooted the VM (I had to force the poweroff as I was getting extra message on the console about sonewconn after the sync message) Hope it helps --=20 You are receiving this mail because: You are the assignee for the bug.=
