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

I had the same problem with core files getting truncated.

Further investigation showed that ulimit -f (aka file size, RLIMIT_FSIZE) also affects core files, so check that limit is also unlimited / suitably high. [I saw this on Linux kernel 3.2.0 / debian wheezy.]
