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". So it means,
may be only 8 samples were taken during the run of over 3 or 4 minutes?

[ From your posting to google-perftools ]

address@hidden google-perftools-0.8]# pprof --text /localdisk/google-
perftools-0.8/profiler1_unittest /tmp/test.3
WARNING: program /localdisk/google-perftools-0.8/profiler1_unittest is
apparently not an ELF file

I didn't see any indication that libunwind is at fault here. Probably
the issue is that pprof is not able to find the correct ELF binary to
map addresses to symbols.

Could you try:


assuming that's where libtool put the actual ELF binary?
