Amit,

Do you receive this error message often ?

this error can be returned under the following scenario:

1) A client makes a new TCP connection to the server (TCP SYN/SYN
ACK/ACK)
2) The new connection is queued on the servers LISTEN socket
3) Client sends a TCP reset (RST) on the connection
4) Server calls accept(2)

[ENOBUFS] No buffer space is available. The accept()cannotcomplete. The queued socket connect request is aborted.

Hi whiteknight,

I've come across this error for the first time, also one more thing, I'm unable to login to the server now..Is it because of this??

Amit,

you say you cannot login into the server, are you refering, you cannot telnet to the server ?

or Application unable to login ?

Hi All,
Thanks for all your support, seems like someone has rebooted the system. All is fine now.

keep in mind that ENOBUFS on accept() is a transient thing, the listen endpoint is still good. any software treating it as a fatal error is buggy and should be updated.
