No Buffer Space Available Linux Socket
running WinSCP on 4 Windows servers (Windows Server 2003 R2). All running WinSCP 4.2.1 Build 428 with the exception of the "problem server". I recently upgraded that one to 4.2.5 in the hopes of fixing the problem. https://community.hpe.com/t5/System-Administration/ftp-tcp-accept-No-buffer-space-available/td-p/2864922 The problem begain with 4.2.1 and continues with 4.2.5 After launching WinSCP, I simply type in the server I want to contact and enter a username. On all of the other servers, I'm prompted for a password and I'm "on my way". On the problem server, I immediately get the error "Network Error: No buffer space available" Request assist - Thanks!

Are you able to connect with any other SSH client? (I suppose you are using SFTP/SCP) Can you try PuTTY? Also please post a full log file showing the problem. To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log._________________Martin Prikryl johncp1962 [View user's profile] Joined: 2010-01-28 Posts: 2 Location: USA Posted: 2010-01-29 20:13 Re: WinSCP 4.2.5 Build 624) No buffer space available [Reply with quote] prikryl wrote: I haven't seen the problem before.

operation on a socket could not be performed because the system lacked sufficient buffer space or because https://trac.filezilla-project.org/ticket/7845 a queue was full.

Perhaps the key to this mystery might be the fact that it seems to occur only when uploading to the server, I was not able to reproduce it by downloading or any other means. On my machines I started seeing the no buffer space error after 17,000~ files were uploaded. I was using standard FTP (no SSL/TLS) with MODE Z disabled. comment:2 Changed 17 months ago by codesquid Status changed from new to moreinfo Do you still experience this issue in the latest version? There had been a few memory leaks which have since been fixed. Note: See TracTickets for help on using tickets.

The communication pattern is n:n,which means 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. Thanks, -Tony c sockets tcp connection share|improve this question edited Apr 15 '12 at 8:29 asked Apr 15 '12 at 8:08 Tony 1131413 Too many open descriptors could cause this error, also MTU misconfigurations and a number of other conditions, I imagine. Impossible to tell for sure without some minimal code example that exhibits the problem. –Michael Foukarakis Apr 15 '12 at 8:13 The error was not "too many open file descriptors" which I met before. I also have these settings: echo 8000 > /proc/sys/kernel/threads-max;; echo 8000 > /proc/sys/net/core/somaxconn;; 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 –Tony Apr 15 '12 at 8:19 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote I had the same problem as your “No buffer space available” error. That echo patch you did is considered as temporary settings. After you change the temporary settings using echo (as described above), you will need to restart the network, which cleared the "no buffer space available" error. You will need to a
