1502.0. "condition-variable morphing problem on V4.0B ???" by TAEC::GARNERO () Tue Mar 11 1997 08:35
Hello,
I have got a problem which seems (to me) similar to the problem
known as IPMT Case MGO102540 (CFS.46628) [condition-variable morphing],
where a thread was blocking on a pthread_mutex_unlock call.
This problem has been fixed on V3.2x.
When the problem occurs, the idle time remaining on each CPU is 0.
As soon as the process (where the problem occurs, ss7_fep_ccitt_c.exe)
is killed (kill -9), the system crashes.
This problem occurs only on multicpus machines.
Could someone tell me if a patched pthread library (on V4.0B) fixing
this problem already exists ?
Configuration:
Digital Unix V4.0B
. with patch 24.00 OSF410-400131 (kit-0002).
. + unofficial patch fixing sigwait problem (EINTR returned even if all
signals masked)
Alpha 4100 with 4 CPUs
pthread interface used: POSIX 1003.1c
Many thanks in advance,
Pierre

_kernel_memory_fault_data_begin:
struct {
fault_va = 0x3ff800d3a98
fault_pc = 0x3ff800d3a98 <<<<<<<<< !!!!
fault_ra = 0xfffffc0000462694

You'd best get me pointers to the compressed dump files
so I can see what's up.

| 1502.2 | Application memory corruptor? | WTFN::SCALES | Despair is appropriate and inevitable. | Tue Mar 11 1997 09:36 | 15 |
| Pierre, there are two separate problems here: there's your thread spinning
in mutex un[b]lock and there's the system crasher. The second is a problem
in the kernel -- i.e., there's nothing that DECthreads _should_ be able to do
that will crash the system. The first occurs because the thread is unable to
acquire the DECthreads scheduler spinlock. While this could be the result of
a problem inside DECthreads, nearly every time this sort of problem has been
reported it's been a memory corruptor in the application.
So, once you've made the system dump available to Jeff, you might want to
examine your code for use of uninitialized local pointer variables, because,
in the absence of any other data, I would suspect a memory corruptor in the
application.

| RE.-1:
Webb, just talking about the mutex unlock, we (DECss7) have already
experienced a similar problem [IPMT MGO102540 (CFS.46628)] on V3.2G.
After 3 months of investigation, it has been proved that the problem
was located in the pthread library.
I am doing, at this moment, a test (on V4.0B) similar to the one which
revealed the bug in the V3.2G pthread library (draft 4 interface) and
I guess that it is the same problem.
Of course, some things have changed in the DECss7 application as we are
now using the POSIX 1003.1c pthread interface.
Anyway, is it sure that the MGO102540 problem is no more in the V4.0B
pthread library ????
At this moment, I am waiting for the official patches fixing this problem
on V3.2x but is there any plan to fix the problem on V4.0B ?
Thanks

| Just FYI the dump in .0 -- looks like a streams-related problem.
Streams guru is investigating.... The crash doesn't even occur
on any of the ss7 threads; it's in one of the kernel's network
protocol threads.
|
| 1502.5 | Maybe not, but there's little data either way. | WTFN::SCALES | Despair is appropriate and inevitable. | Tue Mar 11 1997 13:56 | 14 |
| .3> we (DECss7) have already experienced a similar problem [...] on V3.2G.
True. However, the implementation of thread blocking and unblocking on V4 is
completely different from that on V3, so, while the one stack trace which you've
provided makes it look like a similar problem, there isn't much reason to
believe that it's the -same- problem.
Furthermore, that stack trace would also occur in the corruption case (as well
as a couple of more pathological cases), so there are several possible
explanations. In the absence of more data or a small reproducer test program,
there's not much more we can say.

| 1502.6 | just a hint to save time of anybody | TAEC::GARNERO | | Wed Mar 12 1997 01:42 | 30 |
| RE.-1
Webb,
your are right. I am not sure at 100% that the DECss7 code is correct.
Anyway, my previous experience on this kind of problem shows that
making a small reproducer is quite impossible (we have already tried
to achieve a reproducer when investigating the problem on V3.2G
without any success).
Now, during this last investigation, we have reviewed the DECss7 code
at lot of time, and we haven't found any memory corruption problem.
Remember that an external consultant spend 1 week to investigate the
problem here, at Valbonne. Its conclusion was that there was no problem
on the DECss7 code (related to this problem of course :-)))
And as the problem only occurs on multicpu machine (I have performed
a similar test on a monocpu machine with success) I really think
that memory corruption is not the problem here.
Now, I think we could easily make a small test that way:
. if the problem is located in the condition-variable morphing
optimization (as I suspect), could you generate for me a libpthread.so
which is not implementing this optimization (I think that the pthread
code implementing this optimization is flagged) ?
Thanks in advance for your support,
Pierre

I don't intend to argue about any of the other points, but this statement
deserves some comment.
In fact, you've gotten it entirely backwards. Because the problem only occurs
on a multiprocessor, it is far more likely to be memory corruption. A
uniprocessor, running only one thread at a time, is very limited in the ways
it can creatively corrupt memory. A multiprocessor, running multiple threads
at the same time, asynchronously, has far more opportunities for "creativity".

|
Could someone comfirm that the libpthread.so delivered with V4.0B contains
the condition-variable morphing optimization ?
If yes, is it possible to generate a libpthread.so without this
optimization, please ?
I could check in 5 minutes if the problem is located in portion of code.
Many thanks in advance.

| Pierre,
I have confirmed that in Digital UNIX V4.0* the condition wait morphing
optimization is not enabled.

| As I get the following error message :
DECthreads bugcheck (version V3.13-435), terminating execution.
vpUpcallThreadUnblocked: (os/kern) invalid argument (4) nxm_resched(49,0)
I think that the problem encountered is the same than the one described
in notes 1457,1481,1505.
Could someone tell me when the patch for V4.0B will be available ?
Is it possible to get an unofficial patch now, in order for us to go ahead
in our tests of the DECss7 product (because this problem is blocking) ?
Thanks,
Pierre

| Pierre, the nxm_resched() bugcheck reported in notes 1457 and 1481 is
completely unrelated to the problem reported in this topic. (I'm assuming
that you think, or hope, that they are related, since you posted your reply
here instead of to one of those topics.)
I will allow that a random memory corruptor in your application could cause
this bugcheck, but it's unlikely in the extreme (the corruptor would have to
overwrite a particular field in the thread control block at a particular
time, and the probability of this is much lower than corrupting the
scheduling spinlock). Thus, applying the patch for the nxm_resched()
bugcheck will not fix the corruption problem which you are seeing.
.0> Could someone tell me when the patch for V4.0B will be available ?
I believe that Peter made it clear in 1505 that there would be an annoucement
in this conference when the patch is available. If you need more than that,
you should contact the Digital Unix patch/kitting folks.
