Post subject: Getting an error display, vp_freepkt: Bad file descriptor.

Hello all,
We have developed a bandwidth regulating software in QNX4.5(In application space). We are getting the network packets into the application space using the Virtual Packet Interface(VPI) and regulating them and send it back using the same VPI.
It's working fine with moderate network traffic. But in the case of heavy traffic, it's working but displays the following error message continuously.
vp_freepkt: Bad file descriptor.
If anybody have any idea about this, please let me know.
Thanks in advance
Jith.

Maybe you ran out of file descriptors, and possibly other resources.
Try to increase that (make a new boot image).

Hi all.
As sugggested by Frank, I have build a new boot image with a maximum of
2048 file descripters/process ( Proc32 -f 16 2048 8000) and tried. But no
effect.
Our Bandwidth Manager is showing around 20 times the error message
"vp_freepkt: Bad file descriptor." while transfering a 5MB file at a
bandwidth regulation of 1Mbits/sec, irespective of the available no.of
file descripters/process.(even I have tied with Proc32 -f 16 10240 20480,
then too I got around 20 error messages.).
We have implemented a queueing discipline (CBQ) in the application space,
where we are getting network packets using the VPI (Virtual Packet
Interface) as a IP FILTER. These queueing disciplines keeps the netwoks
packets for a while and send them back in a random order(not in the
sequeuece in which packets are received). Will this make any problem in VPI
(keeping packets for a while in memory and send them back in a random
order)?
Or is there any way to configure the Virtual Packet Interface?
Please give us some solution/suggestion/comments.
Thanks in advance
Jith.
