    Hello,

    Can you reproduce this crash with Ice 3.4.2, preferably using a debug build and without this custom signal handling function?

    Which version of RHEL do you use?

    Best regards,
    Bernard

    Hi,

    We fixed a similar issue in 3.4.2, the issue was related to retries. Upgrade to 3.4.2 as recommended by Bernard, it will most likely fix the problem. The original issue was reported on [thread=5037]this thread[/thread].

    Cheers,
    Benoit.
  • Thanks!
    I will Upgrade Ice to 3.4.2.
