And there are no warnings displayed when using pprof with our program. ELF is not coming up since libunwind is fixed after your help.

Hi Arun, The profiler unit tests works fine. When I tried to profile one of our multi threaded applications, the following happens. 1. When we stop the program, it generates almost 26 Mb of google profiler data. (This is over a period of time) 2. When we try "pprof --gv --lines /opt/tms/bin/mxed /tmp/mxed_profiler_4" , it shows the GV and with only sample. And concentrates only on main thread. We are compiling everything with -g option. Not sure why it is not able to retrieve the data in the 26Mb. ~Rajesh.B On 2/27/07, Arun Sharma <[EMAIL PROTECTED]> wrote: > > [ + google-perftools ] > > On 2/26/07, Rajesh Balamohan <[EMAIL PROTECTED]> wrote: > > export PROFILEFREQUENCY=1000 > > PROFILE: interrupts/evictions/bytes = 10307/4141/657160 > > > > The output of the profiler is saved as follows > > ==================================. > > ls -lrt /tmp/mxed_profiler_3 > > -rw-r--r-- 1 admin root 666921 Feb 26 13:02 /tmp/mxed_profiler_3 > > > > When I run, > > > > pprof --gv --lines --nodecount=200 --nodefraction=0.0005/opt/tms/bin/mxed > > /tmp/ mxed_profiler_3 > > > > I get only couple of nodes and the number of samples says "8".
