Coredump is getting truncated

Question

I am setting

ulimit -c unlimited. 

And in c++ program we are doing

struct rlimit corelimit;
  if (getrlimit(RLIMIT_CORE,          


        

Answer 1

Similar issue happened when I killed the program manually with kill -3. It happened simply because I did not wait enough time for core file to finish generating.

Make sure that the file stopped growing in size, and only then open it.
