OK, so does this mean that increasing the mod_interchange timeout and 
retries are probably no longer relevant to issues related to PSPs taking 
ages to respond?

i.e.
timeout = timeout waiting to get a *connection* to Interchange not waiting 
for a response?
retries=number of times mod_interchange will attempt to make a *connection* 
to Interchange?

So in that case how long will Apache/mod_interchange keep its connection 
open to the Interchange service whilst waiting for a reply from Interchange 
(which in turn, is waiting for the PSP to reply)?  Indefinitely?

So are we any clearer why Net::SSLeay is leading to "terminated output" and 
500 server errors?

Quoting Mike Heins from thread on update to Payment.pm:
"We are having frequent problems with terminated output with
Authorizenet and other payment modules using LWP. Symptom is
a 500 server error from AuthorizeNet, which should be their
problem, but they claim this is not happening and payment
is actually being maded despite 500 response from LWP."

Do we now consider this to be unrelated to the main topic of this thread, 
i.e. the "Interchange stops responding" problem?


BTW, normally it is only necessary for me to restart Apache when the 
Interchange website stops responding.  Does this tell us anything about 
whether it is Apache, mod_interchange, or the Interchange service that has 
"locked up"?  Or could it still be the Interchange service thats locked up, 
but this somehow frees itself once Apache is restarted (e.g. perhaps 
allowing the "locked up" Interchange processes to die)?

BTW, *after* restarting Apache I get the following errors in the Interchange 
error.log:

Do the above errors give us any hints or would you always get these errors 
by restarting Apache whilst Interchange is running?

   } while (!defined $r and $!{eintr});
