What does "Accept() fail" mean?

Post subject:  What does "Accept() fail" mean?
My new router, (D-Link DSL-2640R) has been running for a few days now and the connection seems a lot better than it was, but I have one question.

I was looking through the System Log, to make sure that the error I had been getting was no longer there and I noticed that there were a couple of entries where it said "Accept() fail"

I did try doing a search but couldn't find any useful information. Do you guys/gals know what it means?

TIA

John

:)

Update: I forgot to mention that I have also just changed the Idle out time from 30 minutes to always on, so it wouldn't surprise me if the message went away, as these things seem to do, but I'd stll like to know what it means! ;)

Well every logging system is different.

But I'd guess that it's failing to accept a connection?

Could you post the log entry and those that precede it for context?

I'll have another look at the system logs when I get home, but I am kinda hoping that they'll be gone by then, never to return!

OK, here's the System Log...

I'm also slightly converned about the top few entries... :?

As all those entries happened within the same timeframe, I'd be inclined to believe they were all part of the same process.

As you had your default timeout set to 30 mins its going to drop the connection to your ISP after 30 mins of inactivity on the line. it will automatically reconnect when the router is asked for an external connection.

I think this will be one of 2 events:

1: automatic restart of the connection, hence the polling of the line state and passing of credentials etc
2: outage caused by ISP due to system upgrade or work on the line (check with ISP for work logs/outages)

the accept()fail is likely to be the passing of redundant commands. the fact its appearing after successful connection means its not critical to operation, it may be SNR or other quality parameters it doesn't really like.

It may be a failure in an NCP (Network Control Protocol) negotiation. This might indicate that a Network layer protocol that is being negotiated is not supported by one end of the connection. This may well not be an issue as other protocols are supported and can be used.
