Hi, We have a host running samba under -stable 4.10, and quiet frequently it becomes uresponsive, hitting ^T gives load: 0.00 cmd: ls 12807 [sbwait] 0.00u 0.00s 0% 160k so my guess is that we are running out of some resource (socket buffer). so, if this is true, is there some sysctl to increase? danny
