I've set up a website serving files from a NFS backend. The activity is quite high (the machine has reached 40 Mbps), and I've configured a stripping two disks ZFS filesystem as well, as I intended to do some more tests. However, I have a network problem: Sep 19 17:16:18 server kernel: TCP: [X.Y.Z.T]:14301 to [A.B.C.D]:80; syncache_socket: Socket create failed due to limits or memory shortage Sep 19 17:16:18 server kernel: TCP: [X.Y.Z.T]:14301 to [A.B.C.D]:80 tcpflags 0x18; tcp_input: Listen socket: Socket allocation failed due to limits or memory shortage, sending RST These are not innocuous messages, the machine is rejecting connections like crazy. Any ideas? The number of established TCP connections was around 490, and the machine has 2 GB of RAM. Thanks in advance, Borja. ---------------- "The thing he realised about the windows was this: because they had been converted into openable windows after they had first been designed to be impregnable, they were, in fact, much less secure than if they had been designed as openable windows in the first place."
