Trap 000e and Sockets

[Ben]

I have both of those files in my CONFIG.SYS both in C:\MPTN\PROTOCOL.

SOCKETSK.SYS   8-24-14      128,512
AFINETK.SYS      9-20-15      318,976

I rotate my apache logs about once a month. Right now the biggest is around 2 meg.

With respect to netstat -m right now after running 6 hours this is what it shows:

Code: [Select]

mbufs obtained from page pool            = 10304
free mbufs                               = 8484
data mbufs                               = 0
header mbufs                             = 1
socket structure mbufs                   = 75
socket name mbufs                        = 43
socket option mbufs                      = 0
protocol control block mbufs             = 100
routing table mbufs                      = 1585
fragment reassembly mbufs                = 0
clusters obtained from page pool         = 1135
free clusters                            = 486
times failed to find space               = 0
times waited for space                   = 0

I will monitor InJoyFW GUI to see if see if something or someone is hammering the system but usually that will automatically block any IP/Port that is doing so.

[Doug Bissett]

Good point Doug. I however checked both binaries in FC (socketsk.sys and sockets.sys). I think both have the module name "sockets".
So I am not certain if the TRAP screen makes it possible to see the difference which driver is loaded.
Ben your config.sys lists the driver socketsk.sys and afitnek.sys with a letter k before the .sys ?

I haven't seen a SOCKETS(K) trap, for a couple of years. I do see the odd AFINETK (with the K) trap, which is why I made the suggestion. Apparently, the AFINETK trap has something to do with SMP.

I will also mention, that ArcaOS includes a program SOCKTIDY.EXE, that is supposed to keep dead sockets from accumulating. Again, I am not sure if that is available outside of ArcaOS. Apparently, it helps with servers, but I find that it is not good for normal use. Currently, it is started in C:\TCPIP\bin\B4TCP.CMD but it was started in a different place in earlier versions of ArcaOS.

Try this:
DEVICE=C:\MPTN\PROTOCOL\SOCKETSK.SYS /mbuf:512 /mem:3600

You can try higher values for mbuf and mem.
If that stretches the time until next crash then SOCKETSK.SYS likely has a bug on allocating a buffer as the trap tells me that it is trying to copy memory from an address beyond the limit it can access.
I wouldn't know how to fix this error as no source code exists for SOCKETSK.SYS.

[Ben]

OK, Lars.

I have made the modifications, now I shall see what happens.

[Lars]

Forgot:
1) do not add drivers or modify config.sys ordering on this system. That will allow to compare a trap screen with the first trap screen you already posted.
2) take picture of trap screen if trap happens again.
Check yourself the value of CR2 on trap screen: if it is not higher than the first time,you should increase mbufs or mem
3) as an info: mbufs has relation to everything that says mbufs in netstat -m output and mem has relation to everything that says clusters in netstat -m output. Unfortunately I do not know the direct relation.

[Ben]

Thanks, Lars.

No issues yet, but it hasn't been long enough.

One thing of note is that some lines that were static before have changed... as expected netstat -m - posted for those who are following along;

Code: [Select]

mbufs obtained from page pool            = 4272
free mbufs                               = 2888
data mbufs                               = 0
header mbufs                             = 3
socket structure mbufs                   = 77
socket name mbufs                        = 43
socket option mbufs                      = 0
protocol control block mbufs             = 104
routing table mbufs                      = 1141
fragment reassembly mbufs                = 0
clusters obtained from page pool         = 1150
free clusters                            = 878
times failed to find space               = 0
times waited for space                   = 0


[Lars]

It's a good idea to monitor the output of netstat -m over time.
Maybe you can run netstat every 12 hours or so and dump the output to a file. Maybe that tells you something about free mbufs and free clusters.
Increasing these values in config.sys is just a hack to prevent the driver from ever asking for the last available buffer. Because I think that is when it fails.

[Ben]

I have been doing that. Too bad there isn't any way to do that automatically and add the date/time.

Still no crash since adding those parameters though.

[Lars]

I think there is a tool called chron that allows you to run an application on a time schedule. I think it is installable via AN package manager ( it is hosted at Netlabs,ported by BWW).
It should also be possible to write a REXX script by calling a tool called sleep to put the script to rest. In the REXX script you can write to the log file whatever you want,including time and date.

[Ben]

I can do the scheduling through DragText, but writting the REXX is a hit and miss process for me.

I will take a look through Hobbes; maybe there is something there that I can adapt/modify.

Hi Ben,

I have for some years ago used a schedule utility called  schedb2.zip it adds a schedule page to WPProgram objects.

I have used it for clamav update on hourly basis for some years. Easy to use.

Is found on hobbes:

Hello, Rene.

DragText does the same thing, adding a page to every WPS object, and it's one of the essential enhancers that I add upon installing OS/2.
One has to appreciate such a transparent, necessary application(?).

But, I was unaware of schedb2; thanks for the heads up.

[Lars]

Code: [Select]

/* this is a REXX script */

signal on error name getout
signal on failure name getout
signal on notready name getout
signal on error name getout
signal on halt name getout

LogPath = VALUE('LOGFILES',,'OS2ENVIRONMENT')
LogFile = LogPath'\netstat.log'

'@del /F 'LogFile' 2>&1 >NUL'
rc = stream(LogFile,'C','OPEN WRITE')

'@rxqueue /CLEAR'
say 'Press any key to end ...'
do i=1 to 10
   '@netstat -m | rxqueue'
   string = '********************************************************* 'Date()' *** 'Time()' ***'
   rc = lineout(LogFile,string)
   do j=1 to queued()
      parse pull string
      rc = lineout(LogFile,string)
   end
   if chars() > 0 then do
      leave
   end
   '@sleep 3600s'
end

getout:
rc = stream(LogFile,'C','CLOSE')
return 0


[Ben]

Thanks for that Lars.

Just incase  you are wondering, I haven't had a Trap since I changed my CONFIG.SYS as you suggested.

Hopefully the problem has been solved.

Now, I can move onto, (or back to), the other issues.

[Lars]

Let's hope it's going to stay that way.
