Still need help re: No buffer space available From: "Ronald F. Guilmette" Date: Fri, 16 Apr 1999 12:28:19 -0700 Message-ID: <20875.924290899@monkeys.com> Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG HELP! Nobody ever sent me *any* response to the following query. I am desperate for an answer. The same exact problem has struck again... `No buffer space available' when trying to open a socket, and as a result, a critical application crashes. This time something new also appears to have happened at the around the same time, i.e. the kernel message log seems to have been filled up with a TON of messages that all say: rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) rtfree: 0xf591a700 not freed (neg refs) What the devil goes on here?? This is all happening on a stock FreeBSD 2.2.8 system. (Ain't that supposed to be ``stable''?) ------- Forwarded Message To: questions@freebsd.org Subject: No buffer space available From: "Ronald F. Guilmette" Date: Sat, 03 Apr 1999 14:35:21 -0800 Message-ID: <20431.923178921@monkeys.com> Sender: rfg@monkeys.com I have a program that opesn a LOT of sockets simultaneously. It occasionally dies because it gets a `No buffer space available' error when trying to create yet another socket. I have already reconfigured my kernel (2.2.8) so that I have maxusers set to 192 and also NMBCLUSTERS set to 24576. OK, so what ELSE do I need to do in order to make this error go away? What is the name of the kernel parameter that determines how much space the kernel will use (at a maximum) for socket buffers? P.S. I really don't think I am anywhere near to running out of physical memory. The box in question has just ooodles and oodles of it. ------- End of Forwarded Message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
