Hi all, Are there any known bugs or config problems etc that might be able to cause mbufs on a FreeBSD box to be completely utilised? This is not under high load - its during the down time, and they are completely used within 5 minutes, whereas the cache has been running under much higher load all day. I believe I have narrowed it down to specific traffic - a machine behind the cache was mirroring content - getting only 206 messages (partial content). Could this be the cause? Thanks in advance Dave
