Hello, I just read the attachments in http://lists.dragonflybsd.org/pipermail/users/2012-October/017536.html, and the hang described in one of the attachments reminds me of a problem I encountered with NetBSD 6 recently. (It may have been with RC1; I'm not sure).
I was transferring a DVD iso (using SFTP) from a Windows laptop to my NetBSD system, but suddenly I noticed that my NetBSD system stopped responding. I went over to it and moved the mouse-pointer around a little (worked). Key-presses wouldn't do anything, and when I pressed Ctrl+Alt+F1, the mouse-pointer disappeared (the X screen remained on screen), and I couldn't do anything other than reset it. When I think back, I recall noticing that I got brutally high throughput during the transfer; which raises the question: Is there any known "heavy load" bug lurking which causes the postgresql benchmark and high-throughput transfers to hang the system? -- Kind regards, Jan Danielsson
