Registry Crash

Well, I'm afraid my crash from earlier now happens anytime I try to make an update.

If I login to the registry via icegridadmin, open the application, and make any change whatsoever, as soon as I "Save" the registry crashes. here's a backtrace:

  • If it's of any help, I also did a little poking with gdb:

    (gdb) p this
    $3 = (Ice::Identity * const) 0x82bc228

    Note that this debug session was different than my earlier backtrace, so the addresses won't be the same between the two.

    Hmm, I don't know why it's crashing when it's trying to destroy the string from the Ice::Identity. It sounds like a memory corruption issue. Could you by any chance send me your registry database by email at You just need to tar and compress the content of the directory specified with the IceGrid.Registry.Data property. I should be able to reproduce the issue with your database if this now occurs for each update.

    Btw, which Linux distribution are you using and are you using Ice 3.2?
