But this time a Control-T reports a different state: zio->io_cv load: 0.04 cmd: rsync 98579 [zio->io_cv] 89.97r 0.04u 0.09s 0% 8108k No luck getting a procstat to run -- it just locks up upon issuing the comm= and, and it is highly unlikely this is possible once the system gets into this state. If there us a way for capturing this when it happens, please advise. --=20 You are receiving this mail because: You are the assignee for the bug.=
