	Eugene,

	I am sending to you my developement tree smtpserver version.
	It SHOULD log to the  smtp-server log a line about  "accept()"
	and some error message if the accept() gets some unknown
	error status and dies due to that.

	I have experienced similar problems under heavy loads at
	Solaris 2.3, and Solaris 2.4.  No similar reports so far
	with 2.5(.1).

	These addresses are -- "interesting".  Propably your
	GDB reports garbage, as s_buffer's address is around
	0x0003f000, and is propably the last named variable
	in the program.  Definitely it is not near the end of
	the address space.  That crash address is most likely
	in libc.    Hmm.. 2.5.1 has everything in user-space
	below 0xe0000000, perhaps that is in kernel space ?
