Rsync hanged after 1 GB of data was transferred. Tried a second time. Rsync hanged after 10 GB of data was transferred. Also tried running rsync on linux machine to push data to Freebsd machine. Error message after rsync ran for a while ------------------- rsync: error writing 16385 unbuffered bytes - exiting: Broken pipe rsync error: error in rsync protocol data stream (code 12) at io.c(463) --------------------- After this, I ran rsync on the actual machine itself to pull data from the linux machine. The next morning, the system hanged - screen and keyboard freezed, had to switch machine off and on again. Error message on the screen: -------------------------- Fatal trap 12: page fault while in kernel mode fault virtual address = 0xa130 fault code = supervisor write, page not present instruction pointer = 0x8:0xc034a674 stack pointer = 0x10:0xd6fdbc5c frame pointer = 0x10:0xd6fdbc60 code segment = base 0x0, limit 0xffffff, type 0x1b = DPL0, pres 1, def32 1, gran1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 216 (rsync) interrupt mask = net tty bio cam trap number = 12 panic : page fault syncing disks .... ------------------ I didn't enable dump. Can anybody advise? Thank you very much in anticipation. >How-To-Repeat: ? >Fix: ? >Release-Note: >Audit-Trail: >Unformatted:
