I've no more information about the crash evoked in my previous message,
but last mail of "Ralph Kutschera" (Unknown panic action) points my
reflexions about "Why my server seems to be hang when a panic action ??"

The answer is pretty simple, i've no "panic action" in my smb.conf, and
in the man i can read "Default: panic action =".

But if i type the following command :
# testparm -v | grep panic
I've got :
	panic action = /bin/sleep 999999999

I don't know why in samba 3.4.2 the new default for panic action is
/bin/sleep 999999999 but if i do a simple calcul, this means that my
server sleep during 31 years when a crash appears !!!!!!!!

31 years... it's long, so i'm going to activate a REAL panic action in
my smb.conf !!

This can't resolv neither my ldapsam problem (bug #6771) nor my smbd
crash when mounting some CIFS under linux (and even nor my problem of
broken compilation over CIFS share), but i think my would be more
efficient without sleeping 31 years !!
