 # lame quickie script to snarf a core of a hung asterisk process.
 # bugs to ast_grab_core, blinky-lights.org  (derrick daugherty)
 
+# we have found that gcore doesn't yield as useful a core file
+# as that yielded by a signal-caused core dump. So we are going to change
+# the strategy to sending a SEGV signal to the asterisk process,
+# and have it 'burn to the ground', leaving behind a core file.
+# the main difference is that you cannot control where the
+# core file will end up. We will assume that safe_asterisk was
+# used to start asterisk, and the core file should therefore end
+# up in /tmp (because safe_asterisk cd's there before starting asterisk).
+# if this is not the case, set DUMPDIR to the place where the core
+# file can be found.
