This means that your network memory buffer is not enough to your network traffic. if you are using FreeBSD, put in your /boot/loader.conf : kern.ipc.nmbclusters="8192" kern.ipc.nmbufs="32768" you can see if the problem is it with the command: netstat -m > [root@pituba root]# netstat -m > 1650/2000/4096 mbufs in use (current/peak/max): > 1469 mbufs allocated to data > 124 mbufs allocated to packet headers > 57 mbufs allocated to socket names and addresses > 1024/1024/1024 mbuf clusters in use (current/peak/max) > 2548 Kbytes allocated to network (82% of mb_map in use) > 8436 requests for memory denied > 71 requests for memory delayed > 0 calls to protocol drain routines Its nothing related to hardware problem -----Original Message----- From: owner-freebsd-security@FreeBSD.ORG [mailto:owner-freebsd-security@FreeBSD.ORG]On Behalf Of Eric Anderson Sent: Wednesday, November 14, 2001 11:16 AM To: Sven Giersig Cc: freebsd-security Subject: Re: listrl0: no memory for tx I have seen similar messages on an NFS server that was extremely overloaded. I did a few sysctl tweaks to the tcp window sizes and such, and a few other things, so the machine could keep up with the hundreds of P4's beating the crud out of it. If it's your firewall, I'd be looking at it with a fine toothed comb right now.
