I'm having trouble tracking down the cause - hopefully someone can help! I've checked the following: (1) File handles: cat /proc/sys/fs/file-nr 4672 0 810707 I'm reading this as (allocated, http://serverfault.com/questions/614453/no-buffer-space-available-on-connect unused, available) so this looks OK. (2) Sockets or TCP memory: cat /proc/sys/net/ipv4/tcp_mem 191889 255854 383778 cat /proc/net/sockstat sockets: used 579 TCP: inuse 169 orphan 0 tw 245 alloc 187 mem 5 UDP: inuse 31 mem 4 UDPLITE: inuse 0 RAW: inuse 0 FRAG: inuse 0 memory 0 Reading this as only a total of 579 sockets in use, page totals way below the maximum. There are lots of random TCP tweaks shown on Google - what I'm hoping for in an answer is (1) the resource I'm running out of, (2) how to determine the current value and (3) how to adjust the ceiling. Most of the pages I've found are missing everything except (3)! ** Update #1 ** On Flup's suggestion I did a systrace when it happens (using ping): socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4 connect(4, {sa_family=AF_INET, sin_port=htons(1025), sin_addr=inet_addr("10.140.0.65")}, 16) = -1 ENOBUFS (No buffer space available) ** Update #2 ** I don't know much about the linux kernel source, but I had a dig around and the only place in the connect() path I can see ENOBUFS is here: http://lxr.free-electrons.com/source/net/ipv4/af_inet.c?v=3.11#L353 This looks like it is allocating things in the kernel though with kmem_cache_alloc and security_sk_alloc...? li

Join them; it only takes a minute: Sign up TCP connect error “No buffer space available” up vote 0 down vote favorite 1 I got this error when I was testing a home-made distributed key-value store on very large scale (2048 machines), it works fine on 1024 machines. The communication pattern is n:n,which means no buffer space each machine send lots of requests to every one else. I used C TCP socket to implement it, SO_REUSEADDR to recycle those sockets. Can any one give me some tips about the possibilities that can cause this error? The code is complex, It's hard to simplify it and post here without losing necessary logic. So I just want to know all the possible causes to start to debug. BTW I changed settings as: echo 8000 > /proc/sys/kernel/threads-max echo 8000 > /proc/sys/net/core/somaxconn #limit of listen queue, default is 128 echo 8000 > /proc/sys/net/core/netdev_max_backlog echo 10 > /proc/sys/net/ipv4/tcp_fin_timeout echo "10000 65000" > /proc/sys/net/ipv4/ip_local_port_range I did this is just for enable maximum number of connections.

Impossible to tell for sure without some minimal code example that exhibits the pro
OpenVZ VPS Posted on 22/01/2010 by dariusz.cieslak OpenVZ is operating system-level virtualization technology that allows to run multiple virtual machines (with dedicated IP addresses) on one box (with shared filesystem). It's like a dedicated server but it's not the one. You have to overcome many limitations: Limits on VSZ memory size (virtual, allocated but no necessary used) memory (dedicated servers and Xen have limits on used memory: RSS) Fixed kernel with modules (no custom compilations here) Limits on inodes allocated etc. One of important limitations is limit of size of unswapped memory allocated to kernel. In this area resides tcpsndbuf.It's summary size of buffers that are used to send data. If the value is low your download speed may be limited and sometimes you are getting error: 105 No buffer space available You can check your limits by executing the following command: # grep tcpsndbuf /proc/user_beancounters tcpsndbuf 174336 1735168 1720320 2703360 2801251 Current buffer usage is 174336 bytes, limit is 1720320 bytes and limit was exceeded 2801251 times (ops!). Why send buffer is the problem here instead of receive buffer? Most of the time HTTP server is sending data - requests are much smaller than HTTP responses. Solutions for this error: Limit concurrent connections server handles Check if unused connections are closed as soon as possible This entry was posted in en and tagged network, openvz, vps.
