We are using QNX 6.21 Standard Edition with Development environment.
CITSM Full-Size Socket 370 CPU Card. The built-in network card is Intel 82559.
When I tried to fetch a big file (more than 20 MB) from other machine via ftp, I always got the “Blown stack handling 0x102, see “stacksize” option”. I have tried different stacksize for “io-net” option (from 3000 to 11648 or bigger) by changing the /etc/system/enum/include/net file, it always has the same problem.
By “nicinfo” we could see the Media rate is 10.00MB/s Half-Duplex UTP since we are using a hub. If we use high speed connection (100MB/s Full-Duplex UTP), there would be no problem at all. We could easily transfer file with more than 100MB.
As a matter of fact, we do have to use the slow network 10.MB/s, then how could we get it work?
Yeah, ok. Just checking… Does sloginfo show anything interesting? The other option is to make the stack really large - although I can’t imagine why that would be required other than a bug of some sort. I have certainly ftp’d files larger than 20M without problems - albeit with a different network driver.
Ge something wrong while start up:
scsi_interpret_sense: error=70, sense=5,asc=24. ascq=0
scsi_interpret_sense: SKILLEGAL command 35 in datatype
Sorry don’t know why and how that happened.
Nothing for the transmission though.
It seems io-net (8 of them) got into the some sort of deadlock situation. BTW, we do have QNX 6.2.1 running perfectly on other machine which has the different hardware.
The scsi_* stuff is just from the disk startup - even if you don’t have a scsi drive, eide uses the same commands and you will see complaints if you have a drive which isn’t 100% compliant - often a CD drive.
So it appears you have bug. Report it to QSS and see what they say. Good luck.
