https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211990 --- Comment #5 from Ben RUBSON <ben.rubson@gmail.com> --- I made further troubleshooting. Regarding the number of iscsid processes which increases, I've found timeout settings which permit to always have only one process per target : sysctl kern.iscsi.login_timeout=3D85 sysctl kern.iscsi.iscsid_timeout=3D5 sysctl kern.iscsi.ping_timeout=3D5 These are based on net.inet.tcp.keepinit which is 75000 by default (75 seconds). Regarding the "30" processes limit, it can be tuned with the "-d" option to iscsid (through /etc/rc.d/iscsid for example). And the most important, regarding the bug : when devices do not want to correctly reconnect, I found that it is because iscsi is stuck in the following : cam_sim_free(is->is_sim, TRUE /*free_devq*/); However I don't know why. --=20 You are receiving this mail because: You are the assignee for the bug.=
