Subject: Kernel panic when moving lots of data over network X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 09 Jul 2003 17:53:37 -0000 Hello. Strange problem on a new server we're setting up. It's very stable, except when moving a large amount of data onto it via the network. I begin moving approx 4GB of data onto it, and before the xfer can complete, the system panics and reboots. (I am generally able to get from 1 to 2 GB transferred before the panic occurrs.) I don't know if it matters, but the data transfer is over SSH, like this: ssh root@host tar -cf - -C /usr/local/bigdir . | tar xpf - -C /other/bigd= ir (I issue the ssh command from the machine I am having problems with.) Any help would be greatly appreciated. uname and backtrace data: Script started on Thu Jul 10 10:40:41 2003 [hostname:/usr/local/crash]# uname -a FreeBSD hostname.mind.net 4.8-RELEASE FreeBSD 4.8-RELEASE #28: Thu Jul 10 0= 9:22:07 PDT 2003 toor@hostname.mind.net:/usr/src/sys/compile/HOSTNAME = i386 [hostname:/usr/local/crash]# gdb -k kernel.debug.2 vmcore.2=20 GNU gdb 4.18 (FreeBSD) Copyright 1998 Free Software Foundation, Inc.
