Re: problem with ns2.1b3

[Polly Huang <huang@catarina.usc.edu>]

Arnaud,

A new set of validation test (session simulations) was added to the ns2.1b3 
July 11 release.  The test outputs have to be generated by namtrace-all 
because trace-all (most multicast validation tests use) doesn't support 
tracing for session simulations.  namtrace-all works fine for some of us 
but apparently not all.  Could you describe the hardware and os you're  
using?  Also, are there others encounter the same problem with the 
session tests?

Commenting out namtrace-all only avoids the segmentation fault.
I hope the validation test still alarms you with 'some tests fail'.

Regards,
-Polly
