Each nic is connected to a 3com 100Mbit hub (half duplex!) which is wired to a second proliant (traffic analyser and also cold standy for the gateway), and each to a 3com switch model 3300 to which the nt, sco, and true64 servers and pc hubs are connected. Three of the six lans are connected to a cisco wan router. Disk configuration: RAID-1 setup with 2 9.1GB wu2 scsi disks on a compaq smart array 3200. The custom kernel is ipfw enabled: options IPFIREWALL options IPFIREWALL_DEFAULT_TO_ACCEPT options DUMMYNET but firewall_enable is currently set to "NO". The system used to run FreeBSD 4.0, without the raid controller, and there was not a single problem. Since the "upgrade" it crashes irregularly 2-3 times per month. There is no crash dump or anything in /var/log. I have no screen dump of the panic screen (should we have a camera in the computer room?). After a few minutes the system resets itself. At times there are notifications in /var/log/messages like: Jul 3 01:43:31 irsdevgate /kernel: de1: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) Jul 5 09:29:42 irsdevgate /kernel: xl0: no memory for rx list -- packet dropped! There is, however, no correlation between the occurence these messages and the time of crashing. >How-To-Repeat: There appears (as yet) to be no link between the moment of crashing and external (network) or internal (e.g. cron) activity. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
