I think I have a system that is leaking mbufs and I'd like some ideas on how to track down what mbufs are in use.
Background: The system is running 4.9p1 and has been up for about 8 months. I haven't noticed any problems before. This afternoon, I opened an xterm, did an slogin to another system and ran "ipfw l" on that system. The output froze about halfway through and I noticed that my system was barely responding. A check of the console showed that the system was out of mbuf clusters (1024). I killed a couple of ssh sessions and the in-use mbufs and clusters dropped to 440 but that still strikes me as excessive. My laptop shows 12 clusters in use with a maximum of 74 after a month of uptime. The system in question is my main workstation at work. It has dual heads with a virtual WM and I tend to have lots of xterms open (maybe 50-60, both local and ssh). It's an NFS client but not server. netstat showed only a couple of dozen TCP sockets, though there are a lot of Unix domain sockets (for X) - none had any data queued. Is there any easy way to work out where all the mbufs have gone? -- Peter Jeremy _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
