io-net hang problem

Customer has an application where a server launches a thread eveytime
a client connects to a socket.
The thread reads data and writes to a file from the client until
finished, and then exits.
The code is essentially out of Richard Steven’s book.
The server is running on 2.4 P4, using Realtek NIC.
The client (if not on the same machine) is
another PC.

The number of threads they tested with is 100.
They write 8 kilobytes/second per connection.

Two problems:
When writing to the file using fopen/fwrite/fclose, io-net
seems to hang at some point. All threads are then blocked
on io-net, in the read call. Utilities using io-net
such as netstat and ifconfig also hangs.
When changing the above to use open/rad/write/close,
there is no problem.
Is this a known issue?

When moving the client to the same box as the server,
the same thing happens, even if open/write/close
are used: io-net hangs.

Under 10 client connection, things appear to be ok
even if fopen/write/fclose calls are used.

Any ideas on these?

Thanks

We just ran into a similar problem, and as Sean pointed out, the
“threads” parameter on the TCP/IP stack controls the number of
simultaneous blocking operations, and the default is 48.

We modified /etc/system/enum/include/net to pass the “threads” parameter
to io-net during normal startup, and that fixed it. Our file look like
this:

all
set(IONET_CMD, io-net -ptcpip
“stacksize=16384,threads=512,external_arp,forward”)

We increased the stack size only because we’re doing some logging in one
of our filters, and calling the slog functions overflowed the stack with
the default size.

Great!
Thanks, will try this one.

That’s an awfully large stack considering the default is 2912. slogf
puts approx 1k on the stack so I’d imagine 4k should suffice. You can
also use slogb and a static buffer (mutex protected if necessary).
severity | _SLOG_TEXTBIT means text (I don’t see that doc’d anywhere).

No, I had the same problem with the devb drivers calling slogf out of
an io-blk thread, I had to increase my stack to 12k solely for that.
I think the reason is backwards-compatability; note that earlier proc
versions did not support slog via SYSMGR_COID and so reverted to using
open("/dev/slog", O_WRONLY) - we all know what a stack pig open() is :wink:

True, I think we found it worked ok with 8k, but we have plenty of spare
memory and wanted to be safe. Just out of curiosity, why does the stack
implement its own tasker instead of using native threads with dynamic
stacks?

I think that’s still the case but the stack attempts to initialize the
slog fd at startup, from a real thread so the open() shouldn’t occur
from a stack restricted “thread”.

I answered this in response to your email but didn’t notice the
“nospam” you snuck into your return addr.

My understanding is that our tcpip stack is a port of a BSD kernel
with the non-TCPIP parts stubbed out, and that inside that kernel
all its threads are “run to completion” and use a lot of global
variables, so it would be major additional work and testing to
make the stack safe for pre-emptible threads.

I just encountered an io-net hang problem. I am running 6.20 NC.
I tried to include all of the diagnostic dumps I could think of.
I have already rebooted, so if I missed something it’s already too
late.

These are the net related utilities I was running at the time:
tin
2 voyager sessions
cp a large file (248 MB) to an NT server

a ping attempt to another machine on the same wire resulted in:
ping: sendto: No buffer space available

These are the diagnostic dumps I have included (in order):
nicinfo
pidin
pidin in
ping 192.168.2.5
pidin ar (this was done after the reboot but command lines should be the same)
