the way it should work is your shell communicates the ulimit to the kernel and |
| 7 |
then the kernel will generate the .core upon a crash ... so either your |
| 8 |
kernel is broken or the ulimit->busybox->uclibc->kernel chain is broken |
| 9 |
|
| 10 |
you can check the latter pretty easily by doing something like: |
| 11 |
$ strace -f -o out sh |
| 12 |
$ ulimit -c unlimited |
| 13 |
$ exit |
| 14 |
then in the "out" file, you should see proper calls to getrlimit()/setrlimit() |
| 15 |
for RLIMIT_CORE ... |
| 16 |
|
| 17 |
as for the former, keep in mind it is possible to entirely disable ELF core |
| 18 |
support in the kernel ... verify CONFIG_ELF_CORE is enabled |
