Duc,
Sorry about that.
As far as I know there is no good coverage of possible error messages in the I/A
system in Foxboro's documentation. The ICC manual does a fairly good job of
trying to identify errors you are likely to see in the ICC though.
I can tell you how I think the message breaks down though (anyone who knows
better please feel free to step in with corrections - this is based on my
limited experience digging into other error messages):
FAIL 5 load 23FS01!C0704: Mon Aug 28 08:37:32 2006
iccdrvr.tsk log entry showing command and FAIL status of that command and the
time it occured.
-15
I'm having a little trouble with this "-15" - probably just means ICC error, see
/opt/fox/ciocfg/api/examples/iccdt.h
ICCload error:
iccdrvr.tsk says it the error return code was from an ICCload call.
class= 1
OK, this tells us that the error was an IPC error (different error classes are
listed in /usr/include/fox/iccapi.h). So, at this point we know the ICCload
failed, and the failure has to do with the IPC system. The
error= -29
This is the specific IPC error, E_ABORT_CON -29 "abortion of connect request".
The IPC manual covers what return values you should expect from different types
of calls.
text= icipcmsg: c_chkio error
icipcmsg is an undocumented internal function in iccdrvr (but based on the name
I'd guess it's used for passing ipc messages back to icc), and c_chkio is a
documented iccapi call. I would have expected an E_ABORT_CON response to a
c_send or c_receive rather than a c_chkio though.
After all that, it's still hard to tell what caused the problem. When you use
icc (or iccdrvr) to interact with a CP, an IPC connection is opened between your
workstation and the CP. It appears that this connection is failing.
Regards,
Kevin
