io-pkt-v4-hc (6.5.0SP1) memory leak??   
I'm seeing about a 4K memory leak from io-pkt-v4-hc.

I have QNX 6.5.0 SP1 installed.

I have three io-pkt-v4-hc loaded.  Two of them show memory leaks... 
1.  Connected to enet.
2.  Conneded to wifi.


# showmem -P 

Process listing (Total, Code, Data, Heap, Stack, Other)

 1097728     106496      53248     843776      94208          0       24594 io-pkt-v4-hc
  3297280     974848      57344    2166784      98304          0      122906 io-pkt-v4-hc


a few minutes later.


  1105920     106496      53248     851968      94208          0       24594 io-pkt-v4-hc
  3305472     974848      57344    2174976      98304          0      122906 io-pkt-v4-hc

clearly we can see that the io-pkt-v4-hc's Heap is growing.

Any help would be appreciated.

Is there any type of networking activity occurring on those two 
instances? Or are you seeing the increase in memory consumption with the 
interfaces configured or unconfigured?

Re: io-pkt-v4-hc (6.5.0SP1) memory leak??   
io-pkt uses a pool allocation mechanism that at startup can slowly grow until a steady state is achieved after a few 
minutes. Is this "leak" shortly after startup or is it once io-pkt has been running for a while?

Also check with "netstat -m" to see if the memory leak is perhaps an mbuf leak.

Do you have any ppp interfaces? We have addressed a leak in ppp dial on demand.

Thanks for the quick replies.

Gervais --
    Yes there is "some" networking traffic.  
   I have a dhcp client running on both interfaces.
   I have telnet running on one of the interfaces.
  I'll look at the unconfigure to see if that yields anything

Nick --
   This is a leak.  Memory will keep disappearing until the system "crashes".  I can't fork, I can't do anything.
   I'll check the netstat -m 
   no ppp

Which devnp drivers are you using and can you confirm the version by 
copying the output of "use -i" for each?

io-pkt-v4-hc -ptcpip prefix=/alt &  <- this is in my build shell, this one doesn't ever leak.


io-pkt-v4-hc -dasix -ptcpip prefix=/alt2  <- this is the one that leaks.

 use -i io-pkt-v4-hc
NAME=io-pkt-v4-hc
DESCRIPTION=TCP/IP protocol module.
DATE=2012/06/20-13:36:20-EDT
STATE=stable
HOST=gusbuild4
USER=builder
VERSION=6.5.0
TAGID=650SP1-166

To simplify stuff I'm only loading this one right now.  And I have no telnet either, just dhcp.  It's been running for 
about 15 minutes no leak yet.

I'll give it 5 more minutes and then start a telnet session to see if that causes the leak.

There have been numerous updates to the Asix driver, so I can send you an
experimental version. What platform are you running on - x86 or ARM?

Driver attached. This version is a native io-pkt driver.

That driver looks much better.. I'll be testing it now in my "production" world.
I will report when/if I find something.
In addition I will report if everything works.

It seems to be much better.  So I'd say this is now solved.
