[omniORB] Big string transfer gives COMM_FAILURE from C++ client

[Fernando.Matomira at thomson.com ()]

Hello,



I am trying to send a big string (5 MB) as a parameter from a C++
client implemented using

omniORB to a Java service (the ORB is omniORB). This fails with a
COMM_FAILURE exception with only

about 500K read always (but not the same number).

This does not happen when the client is in Java. omniORB is configured
to do transfers of upto 100MB.

All the machines are at the same site and the error happens every time
for the C++ client.

Any ideas?

Thanks

I assume you mean that you have upped the default giopMaxMsgSize
parameter.

What version of omniORB, and what platform? If you're not running 4.0.7
(or 4.1.0 beta 2), please upgrade.

The latest releases have configuration parameters named maxSocketSend
and maxSocketRecv that may help you.

Cheers,

Duncan.

We are running 4.0.7 on Solaris 9

Thanks

bytes requested = 5,033,716 bytes read = 540,372 max wait time = 3,000
total time spent waiting = 3,190"

Doesn't this mean there's a wait timout of 3000 (time units...) and
3190 (time units...) have already been spent waiting for the message
to be read ?
So it's simply a timeout ?


Just guessing...

You could try setting the maxSocketSend parameter to something like
65536 to see if that helps, but I think it sounds like it could well
just be a timeout on the read, as Stefan suggested.
