So, I have seen a lot of random issues with the PLM reconnect code.  I have made a new branch that adds an INI setting for enabling this, it is disabled by default.  If you have PLM issues, or the prior code had bad effects on your setup, please read and testout the following code:

Please let me know how it works for you.

Hi Kevin.  I turned up the insteon debug level to 4 and ran misterhouse directly from the command line.  I also added two logging statements to bin/mh:

  # Recommended Steps to Close a Serial Port from CPAN
   ::print_log("Attempting to close:  $name  port:  $port" );
   $Serial_Ports{$name}{object}->close() || ::print_log("[Insteon_PLM] Close of serial port failed.");
   ::print_log("Closed." );

Here is the output right before a hang:

Obviously it's hanging on the close.  Kill -9 on the process does not stop misterhouse.

Other info which might be useful:

# perl -e 'use Device::SerialPort 9999'
Device::SerialPort version 9999 required--this is only version 1.04 at -e line 1.

And when I run the following script:

#! /usr/bin/perl -w

use strict;

use Device::SerialPort qw( :PARAM :STAT 0.07 );

my $PortName = '/dev/insteon';
my $ob = new Device::SerialPort ($PortName, 0) || die "Can't open $PortName: $!\n";
my $baud = $ob->baudrate;
my $parity = $ob->parity;
my $data = $ob->databits;
my $stop = $ob->stopbits;
my $hshake = $ob->handshake;

print "B = $baud, D = $data, S = $stop, P = $parity, 
            H = $hshake\n";

print "first close OK\n";
print "second close OK\n";
undef $ob; 

print "third close OK\n";

I get:

B = 9600, D = 8, S = 1, P = none, 
            H = none
Request to send
Data terminal ready
first close OK
second close OK
Can't call method "close" on an undefined value at ./ line 35.

which is pretty much what I would expect.

Jim, this looks like this is a bug that was introduced when I added the feature to reconnect the PLM.  It seems like this is something specific to Gentoo, which I know nothing about.

I am hoping that perl is providing some error messages that might help diagnose the problem.  Can you enable level 4 debugging for insteon? And run misterhouse from the command line and not as a service?  The next time this error occurs, can you send me the command line output around this error?

The current insteon code on the master branch is causing me issues.  I am running misterhouse on a 3.12.13 gentoo box.  At some point, either during start up, or while trying to control lights through the web interface, I get the following:

13/05/2014 05:58:07 PM [Insteon::BaseObject] received engine version for $kitchen4_back_master of I2. hops left: 0

13/05/2014 05:58:09 PM [Insteon_PLM] WARN: The PLM did not respond to the last command. The port may have closed, attempting to reopen the port.

At this point, Misterhouse freezes and becomes unresponsive.  When I try to restart the service:

# service misterhouse stop
 * Stopping misterhouse ...
 * start-stop-daemon: 1 process refused to stop
 * Failed to stop misterhouse                                                                                     [ !! ]
 * ERROR: misterhouse failed to stop

Trying to kill -9 the misterhouse process has no effect.  I need to reboot.  I've tried resetting the usb port, but that too hangs when it gets to the PLM. 

After downgrading to stable, I am no longer experiencing freezes.  I am still unable to cleanly stop the misterhouse service; but this is something I probably would not have noticed as I do not ordinarily do this.
