FreeBSD newmail.function.com 4.9-RELEASE FreeBSD 4.9 RELEASE #0: Mon Oct 27 17:09 GMT 2003   root@freebsd-stable.sentex.ca:/usr/obj/usr/src/sys/GENERIC i386
>Description:
Hardware - Intel P4 2.4GHz 1533
Harddisk - IDE Seagate 120GB
rsync-2.5.6.1

I ran rsync on machine to pull some data (home directories, huge 23 GB) from another machine (running linux) - via SSH on a remote computer.    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.

 The problem may have been resolved.
 
 After failing to do a make buildworld to upgrade to 5.2.1 (an indication 
 of hardware problem according to freebsd documentation, I returned the 
 machine to the vendor.  Vendor verified a problem with the RAM and 
 replaced it.  Now I am testing the RAM.
