FastcgiStub does not raise a new process

Question

Hi there.
we have a perl FCGI running with Sun ONE 6.1 sp5 over Solaris10.
We have a line in obj.conf like this:
<Object name="fcgi.perl">
Service fn="responder-fastcgi" app-path="/usr/bin/perl" app-args="/internet/datos/WWW/cgi-bin/loginCGI/loginCGI.pl" app-args="/inter
net/datos/WWW/cgi-bin/loginCGI" bind-path="localhost:27527" resp-timeout=10 restart-interval=30 min-procs=1 max-procs=10
</Object>
We are doing load test against our web app., and we can see that Fastcgistub does not start a new perl process when needed (and of couerse, we fail in process too many request). Instead of that, when our perl dies due to a SIGPIPE signal, we can see this message in fastcgitub.log, repeated a lot of times:
server bind error
/usr/bin/perl bound to localhost:27527 is already running
Could you help us with this issue, please?
Thanks a lot in advance.
Best Regards

In my test setup :
<Object name="fcgi.perl">
Service fn="responder-fastcgi" app-path="/opt/csw/bin/perl" app-args="/tmp/one.pl" bind-path="localhost:27527" resp-timeout=10 restart-interval=30 min-procs=2 max-procs=10
</Object>
If I overload the CPU using
$ ab -n 100000 -c 100 http://host:port/fcgiperl/
I am able to saturate the CPU. Even if I print a sleep statement in while loop
of /tmp/one.pl then too, I don't get the error you mentioned.
I however observed that Fastcgistub doesn't create the new processes.
Can you test the following script in your test environment to see how
it performs?
--------------------- /tmp/one.pl -----------------------------
#!/usr/bin/perl
use IO::File;
#use strict;
use CGI::Fast qw(:standard);
$COUNTER = 0;
while (new CGI::Fast) {
print header;
print start_html("Fast CGI Rocks");
print
h1("Fast CGI Rocks"),
"Invocation number ",b($COUNTER++),
" PID ",b($$),".",
hr;
print end_html;
