Consumption has failed

On client side (C#), I got sometimes the error below. I not sure where it come from.
Is this something related to "Ice.CacheMessageBuffers" which is set to 1 in .NET
and should bet set to 0 ?
(Ice 3.4.2)

    Hi David,

    The stack trace shows that your code calls operation getGLMTokenDB on an (your) object with ID "140", and get an Ice::ObjectNotExistException. This means that the target object adapter is listening but could not locate an object with this ID. You should review the code in your server.

    This is unrelated to Ice.CacheMessageBuffers.

    Best regards,
  • Ok thanks, I will check it.
  • I used a callback system (like the same name sample), here the client give an eventHandler with a method onEventPrice, which is called by the server when something change.

    Most of the time it works fine. But sometimes, I got this error (so the getGLMTokenDB is removed).
    On the client side, I checked that I used ice_timeout(-1) for the objectprx send to the server.
    Not sure where to look now (may be the prx is garbaged in C#?)

    It looks like a System.NullReferenceException exception is raised by the implementation of the onEventPrice method in your client.

    Unless you disabled dispatch warnings (with the Ice.Warn.Dispatch property), you should get a warning on the standard error output. The warning should show the stack trace of the exception. Do you get this warning?

  • Thanks.
    I will look at this point with the console developer next week
