Possible reasons for heart not terminating after saying it's going to?

[Alexey Romanov]

On startup of my application, I've got the message

{"Kernel pid terminated",application_controller,"{application_start_failure,gmcontroller,{{{badmatch,{error,enoent}},[{eeprom,parse,1},{config,read,1},{gmc_root_sup,init,1},{supervisor,init,1},{gen_server,init_it,6},{proc_lib,init_p_do_apply,3}]},{gmcontroller,start,[normal,[]]}}}"}
heart: Sat Jan  1 21:53:26 2000: Erlang has closed.
heart: Sat Jan  1 21:53:26 2000: Would reboot. Terminating.

and, then it didn't terminate (at least after waiting for 10 minutes).
^C stopped the process without problems.

Yours, Alexey Romanov
