Re: [foxboro] ICCAPI error

Duc,

Sounds like a resource limit has been reached on a station, likely the =
host of the Control Processor, but it could also be the CP itself. Have =
the tech run the "show_params" command on the host to see if one of the =
limits has been reached.

If the tech knows about the Foxboro tool spic, there may be some help =
using that tool.  If the station they were using to run the configurator =
is different from the host of the CP, then run show_params on that =
station, too.

Check the partition sizes free space. If /var/tmp gets full, then some =
configurators do not work well.  Check memory and largest segment on the =
CP's STATION display to see that you do not hit limits.

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=20
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. =20

class=3D 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=20

error=3D -29
This is the specific IPC error, E_ABORT_CON -29 "abortion of connect =
request".=20
The IPC manual covers what return values you should expect from =
different types
of calls.

text=3D 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
