Sorry about that -- someone misconfigured their system and walked through the 
address sspaxce asking for ranges (size 3) and then discarding them and asking 
for more.
I wasn't really expecting such small holes, so kept the allocation code REAL 
SIMPLE -- it give the user *upto* the requested amount from the first chunk.
I see this is a bit of a bummer for you :-((
I may tweak it to look in subsequent blocks ....

As I said earlier, phase (1) and (2) are upsetting phase (3) ...

Basically the WWW interface was calling the SKSP interface and wedging.
WWW then used up all its permitted processes, so the WWW server died.

[[ PERL gurus out there: how can I avoid the "sh -c" process in
	$out = `cmd -a 'arg 1'`;
]]

I have freed the ACK blockage, and made the allocate code not try quite so 
hard, and now our WWW server is back in the land of the living.


The SKSP server is still seeing null sessions which time out after half a 
minute -- a bit of a bummeer :-(

The hosts concerned are decent citizens most of the time (I think ...)
"|23" means "23 seconds after the call started". Any ideas ?
