Hi all

It is with some pride that I discovered today that our Business warp
Server file and print machine and a second PC - Internet gateway server
have both  been up and running without hiccup for 

29days    22 hours and  23 minutes!!!

and the reason for the server stopping almost a month ago was a violent
electrical storm and power failure and the UPS monitor shut things down
cleanly!

Cheers

Good on you Graham.

I trust that you have the latest available kernel which overcomes the 49
day problem.

Yes, sadly folks, OS/2 suffers from a similar problem to the Win-dy
systems. Although one wonders how MS ever found it or considered it a real
issue...

Subject:  Re:  SWAPPER.DAT

Add more real memory !

No really, if you want to limit it's size (and possibly change its location to another
disk), find the statement in config.sys, which may look something like this:

SWAPPATH=D:\ 4096 40960

The first numerical value (4096 in this example) is how much freespace (in kb) you
decided you *MUST* keep free on the drive (in my example, drive D:). When this limit
is reached OS/2 will start popping up messages to say that there's no more space. At
which point, cancel some of your running applications. The second figure is the
initial value to create the swapper.dat file with at boot up. OS/2 will keep
increasing the size of the swapper.dat file as it needs to up to the limit of "must
have free" that you set, however allocating a "chunk" together at the start is more
efficient as the OS has less searching for free space to do.

Best solution is to add more "Real" memory. How much do you have in the system at the
moment ? Although Warp4 CAN run with as little as 4MB, I'd recommend 64 MB for current
applications - more if you're running virtual PC or ODIN.

Cheers/2

Ed.

Hey Graham,

>Oops!  Now you have upset me!  What is the 49 day issue!??

Well, strictly speaking, it's the 49.7 day issue.  There's a variable in the kernel that records 
(from memory) the number of seconds since the system was rebooted.  The problem is 
that the type of variable used only holds enough seconds for 49.7 days.  There's been 
several attempts to correct - we definitely installed one of the Testcase kernels on the 
FIrewall machine in an attempt to prevent this hang at 49.7 days - I think the WSEB 
machine is still running the FP3 kernel.

Most recent changes to do with the 49.7 day hang in the kernel were:
    JR15405: (probably) DosQueryAsyncTimer fails on timecritical thread after
    	     mscount rolls over after 49.7 days of uptime

  20020401   revision 14.088g
    JR15405 part 2: more likely fix for 49.7 day hang (still in test)

  20020802   revision 14.091a
	- Yet another attempt (the last, we hope) to fix the 49.7 day hang

  20020822   revision 14.091b
	JR15405 (final) the 49.7 day change might not have been in 20020802.

  20030213 14.093e
	JR17862 fix a problem with a thread hanging (but not the whole system) 
	  after the 49.7 day rollover doing a DosSleep (*Not* fixed in 1226)

Can't remember where FP3 sits in the above....

Cheers,

Paul.

[chomp]ed Ed's excellent advice.

But let's ask a question, as well...

Is there some specific reason why it has taken over the whole system?
Sounds like a runaway application gobbling up memory until the SWAPPER is
occupying the entire drive and, as Ed said, it then pops up messages at
you.

Is this a bug in newer releases ?  I certainly have systems (some on pretty old versions of code)

To be honest - I don't know.  I gather it must manifest in different hardware combinations in 
different ways.  There have been MANY attempts to fix this - what I posted was just whats 
listed in the readme of the latest Testcase kernels.

Obviously it was a non-trivial thing to fix!!

Paul.

The bug isn't a crash issue (like it is in win9x) all it does is wrap the 
"uptime" counter back to 0 after 49.7 days. The trivial workaround for this 
is to have a small .cmd write a log of boot times and refer to that.

BTW, my record is 619 days. A 12 hr power outage got it in the end (a UPS 
can only do so much :)

Well according to Scott's changelog in the latest Testcase kernels - he fixed a 49.7 day 
hang - so there must have been a hang on some hardware :)  A search on 
groups.google dot com shows posts about the hangs too :)

I would still be searching for the details of the answer....

I do understand that all eCS 1.1 registered users can go to the eCS site
and download the latest kernel 14.094 (not strictly WSEB but given the
common kernel I would expect there is an equivalent download for you) which
is reputed to totally fix the problem.

Interesting note: it seems from Paul's notes to be called the "mscount" -
somewhat ironic!

Well the absolute latest kernels are currently sitting on IBM's Testcase site at 
ftp://testcase.boulder.ibm dot com/ps/fromibm/os2

Hi Alan, Ed,
Although with Warp3 Connect and 64MB RAM, after everything [NetBIOS
etc.] loaded, you still have approx 20MB of RAM FREE, using any version
of Warp4 that will show up as only 512KB of RAM FREE - just sufficient
to run the virtual memory paging mechanism.  If possible with Warp4 and
better I would recommend not less than 96MB or 128MB - depending on the
motherboard's SIMM/DIMM etc., capability - there are very cheap RAM
modules around still. I saw 256MB SDRAM for AU$59 locally - should be
even cheaper in one of the Capital Cities.

Thats not good. I'd be real unhappy if I couldn't get > 50 days uptime.

Not one of the OS/2 servers I've had anything to do with has these sorts of 
problems... and I never heard anything other than rumours about these sorts 
of crashes, which I discounted as bad HW.

As an aside... I wasn't aware of this before now but apparently a lot of
