I have been seeing this error on my RPI installation of HG. It seems to be a mono issue according to the link below.
https://bugzilla.novell.com/show_bug.cgi?id=419989 (https://bugzilla.novell.com/show_bug.cgi?id=419989)
Any suggestions on how to resolve this or if this is HG related?

Are you using python? I've seen a similar problem and perhaps it has something to do with the python engine and mono.
If this is the issue, you may migrate the code to javascript (but for using events/delegates you need the latest hg release).

Yes, I am using python. I don't code much in javascript and even less in C#. I guess I will have to live with it for now.

Hello haitch,
Python and Ruby engines have been just updated in latest testing release (r415):
https://sourceforge.net/projects/homegenie/files/testing/
Let me know if this release solves the bug.
Cheers,
g.

Hi Gene,
I tried again with r415 and the same issue occurred. So I went a head and built mono from source on the RPI and HG has been running for an hour without crashing. Apparently the fix here never made it into the RPI build of mono.
https://bugzilla.novell.com/show_bug.cgi?id=419989 (https://bugzilla.novell.com/show_bug.cgi?id=419989)
I tried testing with r415 but I could not untar the archive.
$ tar zxf homegenie_1_00_beta_r415.tgz

Before building mono I made the following change to fix the tls issue. It is odd that arm is set to 8 when i386 and i686 are set to 32. I am stuck building mono from source till this is resolved upstream.

Seems it to be a problem with mono and BBB?
With official arm debian mono (3.2.8) there is no such problem on RPi and BPi.

I am testing on my RPI.

Are you running homegenie sd card?

I had been running raspbain along with the HG all.deb from source forge. I went a head and installed the HG RPI image and I get the same results.

Does the HG RPI image use the debian version of mono or are you building that from source? It looks like the TLS issue has to be resolved upstream by the mono maintainers.

So a commit was pushed to the mono master branch for the tls issue above, It is unlikely this will make into the debian repos anytime soon. I will have to run a local version of mono for now.
