Hi all, I was testing the stability of modperl
under high loads (Apache sometimes crashes with an error message on my Windows
2000, but once I close the message, it's ok again), and I wrote this very simple
client code:
use strict;
use warnings; #use SOAP::Lite +trace=>'all'; use SOAP::Lite; use threads; $|=1;
foreach my $index (1..80) { threads->new(\&loadTest,$index); } while (1) { sleep (100); } sub loadTest
{ my ($index) = @_; print "Starting thread #".$index."\n"; my $client = SOAP::Lite ->uri('SimpleApache/SOAP') ->proxy('http://localhost:7080/soap/') ->on_fault(sub{print STDERR "Cannot connect to SOAP server\n";return undef;}); while (1) { my $result = $client->ping; next if (!$result); print "$index-".$result->result.' '; } } Notice that I created 80 threads. Seems that after
running for a short a while I get the attached error message. I also noticed
that my memory dropped like crazy during runtime. The perl client died, but
Apache survived (hence my attempt to crash Apache myself failed).
Does anyone know what causes the attached message
to appear? Short of memory (for my system it wasn't at 0 yet; about 17MB of
physical memory left)?
