[ns] validation error

[Pubali Banerjee]

I am getting a validation error after I installed ns allinone 2.27.
The test-all-full fails. The error message is the follows:

(partial error message)
Running test twoway:  
./../ns test-suite-full.tcl twoway QUIET  
ns: _o91 recv 536:  
    (_o91 cmd line 1)  
    invoked from within  
"_o91 cmd recv 536"  
    invoked from within  
"catch "$self cmd $args" ret"  
    invoked from within  
"if [catch "$self cmd $args" ret] {  
set cls [$self info class]  
global errorInfo  
set savedInfo $errorInfo  
error "error when calling class $cls: $args" $..."  
    (procedure "_o91" line 2)  
    (SplitObject unknown line 2)  
    invoked from within  
"_o91 recv 536"  


Does anybody know what this could be? Please help if you can.
  
Thanks much,
