[Bug Report] ----------------------------- Category: Installation Failure Package: ns ns2.34 OS: Fedora 14 Environment Variables: LD_LIBRARY_PATH= TCL_LIBRARY= TK_LIBRARY=
----------------------------- Description: Hi everybody, Im trying to add CBRP to ns2.34. But when I run scripts to test it, if the session is more than 30 sessions (in case of 100 nodes), segmentation fault happens. I use GDB to trace the error and usually get one of 2 kinds of following errors: 1. Program received signal SIGSEGV, Segmentation fault. 0x081c2427 in Scheduler::dispatch(Event*, double) () #0 0x081c2427 in Scheduler::dispatch(Event*, double) () #1 0x081c2374 in Scheduler::run() () #2 0x081c2521 in Scheduler::command(int, char const* const*) () #3 0x083c4a1a in TclClass::dispatch_cmd(void*, Tcl_Interp*, int, char const**) () #4 0x083c8412 in OTclDispatch (cd=0x87f03e8, in=0x8625960, argc=3, argv=0xbfffd920) at otcl.c:434 #5 0x083cee4e in TclInvokeStringCommand () #6 0x083d136b in TclEvalObjvInternal () #7 0x083fba3e in TclExecuteByteCode () #8 0x083ffbcd in TclCompEvalObj () #9 0x083fbf90 in TclExecuteByteCode () #10 0x083ffbcd in TclCompEvalObj () #11 0x0842a2ab in TclObjInterpProc () #12 0x0842a6e0 in TclProcInterpProc () #13 0x083c859a in OTclDispatch (cd=0x87f03e8, in=0x8625960, argc=2, argv=0xbfffe420) at otcl.c:477 2.
