Howdy,

Why the error 11, and what would cause the file to disappear?

/usr/include/asm-generic/errno-base.h:#define EAGAIN 11
/* Try again */

I'm guessing that means the file was opened for exclusive access or the file system was doing something with the file. It's not saying the file "is gone".

Oh, I'm telling you the file is gone.

My outbound directory is left with a bunch of packets and no .?lo file.

If I "watch ls -al outbound.xxx/", I can see sbbsecho create the packet, create the .?lo file.

As soon as binkit goes to send it, it disappears, and the Error 11 is reported at the same time.

Most likely, BinkIt is deleting the file itself immediately after that error is logged.

I would expect to see a "Deleted file: /path/to/flo-file" log message in that case, however, and you didn't show that, so that's suspicious.

I have mail going out frequently (at least every hour), and it is happening every time.

"Try again" doesnt make sense for this - as the file is not there..

I suspect the file *is* there at the moment that BinkIt is trying to open it and is logging that error message.

Looking at the script source (which mind you, I did not write), the File.open() method is be used to open FLO files and in shareable mode, so the file should be automatically retry the open and only return that error after several failed open attempts (usually a noticable delay of several seconds). The 28 second gap between log messages the log output you shared suggests that these open retries are indeed happening.

Is it possible SBBSecho or another process still has this FLO file open at that moment?

It sounds like BinkIt should peform an open-retry when getting that specific open error. Submit an issue at gitlab.synchro.net for someone to follow-up on this?

OK.

Thanks,

Yes, no mention of "Deleted file:" is shown in syslog (from the event server). I do see that when I run it interactively though.

I dont believe so.

My test FTN area (zone 10 "private") is only used by me - and if I am the only person posting a message, sbbsecho does it thing.

Here is an except from that time in question:

2025-06-02 15:42:49 Finalizing outbound packet from 12:1/2 to 12:1/1: /opt/sbbs/temp/sbbsecho/683d39d8.pkt

From this, I dont believe sbbsecho was running (and working on that .?lo) file at the same time binkit was reading it. (Binkit started at 15:42:50, when sbbsecho finished at 15:42:49.)
