According to the libssh2.org site, it is thread safe: "Thread-safe: just don't share handles simultaneously"

I'm not sure if I am sharing handles simultaneously

At the top of my code I call

use Net::SSH2;

Then I create my threads

        my $work_q = Thread::Queue->new();
        my $thr = threads->new( 'file_worker', $work_q );

In my file_work sub I call the sftp_file if the file is found and supply the required arguments

my $retval = sftp_file($file,$destfile,$host,$port,$user,$privpath,$pu
+bpath,$pass);
