I see this most when we get interference on the same channel as someone else when they try to use the channels we are on, causing the access points to go a little crazy. Almost in all cases i have seen it has been from interference from other sources causing the interface to temporally loose link for a few breif seconds or loss of the access point completely due to interference. (We have some companies around here that don't like to play nice, and we have a very crowded radio space.) Just thought i would throw in my two cents. :-) On Mon, 03 Feb 2003 16:10:29 -0600, Larry Rosenman wrote > --On Monday, February 03, 2003 17:06:13 -0500 Bill Moran > wrote: > > > Peter Radcliffe wrote: > >> ping: sendto: No buffer space available > >> ping: sendto: No buffer space available > >> > >> I see this occasionally on my -stable box and havn't had a good > >> explanation of why and what buffer.
