[Ace-users] Re: [ciao-users] Calling ccm_activate on CIAO 0.5.9

[Douglas C. Schmidt]

Hi Santos,

   Your problem sounds very application specific, so I suggest you spend
some time in the debugger figuring out what's going on.  If you can get
this problem to occur in one of the standard CIAO tests please let us know.

Thanks,

        Doug
