Howdy,
Today I discovered SBBS with 2 threads both running at 98% CPU - having stopped and restarted SBBS, its all back to normal.
At the same time, my fido hub alerted me to my system being "slow" and refusing packets. Curious, I looked through the logs and indeed it seems that when I polled my fsxhub, mail flowed normally, but when I polled my fido hub, it was stuck there receiving a file:
Authentication successful:

Receiving file: /opt/sbbs/temp/e8c38a06.pkt (1.4KB)
[no more output]
It doesnt appeaer that this thread dies - (and it should time out after 5 minutes right?) I ran "binkit -p" and it's still stuck on this node after 20 mins.
My fido hub is set to "Poll: Yes", so I'm suspecting everytime my system was polling, the old thread hadnt died yet, so eventually I end up with many threads tied up polling my fido hub.
So, shouldnt it ultimately time out after 5 mins?
Is there a way to "busy out" the polled node, so another thread doesnt try and call it again?

The SBBS event thread is a single thread. BinkIt polling is normally done as a timed event, which is run as in the foreground of
that single event thread. So I'm not clear what "another thread" would be.

I absolutely know WHY something breaks normally. It's just good to reboot once a day to clear up issues that come up randomly. That's how bbses are. shit happens. We are usually running windows and launching legacy software made by hobbyist programmers. We can't be around all the time when something decides to go haywire and if a user can't connect one time they may never try again.
You aren't a sysop, so you wouldn't know that; you just run a website that scriptkiddies scrape to attack us.

It's quite easy to run that stuff on Linux if you know what you're

I switched my BBS over to Linux not too long ago, and to be fair, it
seems there are some DOS doors (in particular, TradeWars 2002) that
don't run in DOSEMU 1.x. I've heard it does run in DOSEMU 2, though I have yet to successfully get DOSEMU 2 working with Synchronet.
However, regarding mro's statement about emulating stuff, I think even a 32-bit Windows uses some kind of emulated environment anyway. Windows
has its NTVDM, the Virtual DOS Machine, though I don't know all the details of how it works. I do know that 64-bit x86 processors are able
to run 16-bit binaries when running in 32-bit mode though..

Is there a way to "busy out" the polled node, so another thread doesnt try and call it again?
The SBBS event thread is a single thread. BinkIt polling is normally done as a timed event, which is run as in the foreground of that single event thread. So I'm not clear what "another thread" would be.
OK, so I have BINKPOLL (binkit -p) set to run 2 times per day.
So are you suggesting that when SBBS runs it, it can never run a subsequent time, if the previous run never completes?
My logs show it does run twice a day (not 12 hrs apart, ergo 2 times a day - but...)
Aug 5 00:35:54 d-11-1 synchronet: evnt BINKPOLL Running native timed event: BINKPOLL
Aug 5 14:36:58 d-11-1 synchronet: evnt BINKPOLL Running native timed event: BINKPOLL
So if the first question is yes, then that would imply that binkit -p does eventually exit.
I'm wondering then, what else could cause the CPU goes to 100% on 2 threads for an extend period of time?
(I havent monoitored the time, but my vmware
logs show it was pegged for 2 hrs before I intervened.)
Since my fido link identified the cause (it seemed it was in his end), CPU is backed to < 5%.

It appeared my fido polled me roughly every hour or so, and what I did notice is the absense of a corresponding:
BINKP service thread terminated (4 clients remain, 4 total, 60 served)
for his polls, when his poll would have ended.
Checking through my logs I see often "[3-6] clients remain" for the BINKP service thread - so that indicates binkp sessions that havent yet exited?
Well if you figure out how to reproduce the problem, let me know.
I might be able to, as I think it is MTU related - and I can revert my MTU configuration back to 1500 to try and get it to happen again. I'm not too worried about fixing it, as it's no longer an issue over IPv4 - so I copied the above for you in case there is another underlying issue with the BINKP service thread and not exiting that you are interested in.

ambrosia start making 4gig datafiles
The problem started when I switched to a new ISP, that uses PPPoE.
As a result all of my IPv6 traffic was affected by the lower MTU,
and while I addressed that for my server LAN, I'm assuming it is
affecting the docker lan (havent definitively confirmed that yet,
but it seems likely).

but never did go that far.

Actually, IPv6 is pretty easy, and I've configured everything to use

I did have NAT64 running as well - I was hoping to do away with IPv4
(dont want to manage both address schemes) - but the switch to PPPoE messed that up.
Everything works fine now with IPv6 - except NAT64 - the MTU threw me
for a bit, but I recall MTU issues in the paste (with VPNs) so it was
easy to validate and fix once I picked that as the issue.
