Hi,
We have run into a memory leaks when accessing performance counters using
Win32::perflib library. Interestingly enough the memory leak only occurs
when getting network counters. The following small test case demonstrates
the problem:
use Win32::PerfLib;
my $perflib = new Win32::PerfLib("");
my $obj = 510; # 230 - proc stat and 510 - network stat
while(1) {
my $proc_ref = {};
$perflib->GetObjectList($obj, $proc_ref);
$perflib->Close($proc_ref));
}
The test case above leaks 100KB/s. Note that if you change $obj from 510
(network) to 230 (process), the leak goes away.
We are running active perl version 5.10.0 built for MSWin32-x86-multi-thread
(with 5 registered patches).
OS: Windows XP Professional.
Thanks,
Vassili
