Subject: Memory leak
Download (untitled) / with headers
text/plain 1.2k
Hi, We're using a build of perl 5.6.1, and Net::SSH::Perl 1.30 (not listed on the 'rt' drop down list!) on various flavours of RedHat/Fedora. We've been tracing a memory leak, which eventually has lead to a subroutine which was creating a new Net::SSH::Perl object each time it was called. However, when leaving the routine (and hence the scope of the object), memory doesn't seem to be being released. The problem can be demonstrated with the following simple script, which will slowly consume more and more memory: #!/packages/ksite/perl/bin/perl -w use strict; use Carp; use Net::SSH::Perl; while (1) { my $sshhandle = new Net::SSH::Perl("", (debug=>0, protocol=>1)); if ( ! defined $sshhandle ) { croak("FATAL:: Unable to make ssh connection.\n"); } $sshhandle->login("root",undef); my ($out,$err,$exit)=$sshhandle->cmd('date'); if ( $exit ) { my $message="FATAL:: Unable to open ssh connection. Error was ".$err; croak ($message); } undef $sshhandle; } We're going to work around this for now by having a single Net::SSH::Perl object, but as I understand things this code should work Ok, and fully destroy all of the data associated with the object each time round the loop? Any help appreciated. Danny

Confirmed with v1.35. With both, SSH1 and SSH2. Seems to grow slower with SSH2 (but that's just a feeling). Steffen -- Steffen Schwigon <> Dresden Perl Mongers <>
