Looks like you lost connection / stopped receiving blocks.
Do not use this post as information for making any important decisions. The only agreements I ever make are informal and non-binding. Take the same precautions as when dealing with a compromised account, scammer, sockpuppet, etc.

Weird because my linux system (same router)
worked fine and signed the block...
And I was listening let's talk bitcoin on the "problematic" system the same time...
so I assume my windows BTSX client loosed connection for some reason.... (not my system)

Man, are you running delegate in GUI? Besides, It might lock unexpectedly.

Actually I have a server with linux mint 17 64bit ,16GB ram, 80 GB SSD + 3860 GB NAS WD HDD, Intel Pentium CPU G3220 @ 3.00GHx2, ASUS RADEON R9-280X , UPS (+NTP time installed)
And a second WIN 7 system that runs in parallel with that, with same delegates activated on both, to play around with the GUI :P

You are not supposed to enable delegates on 2 separate machines.
From what I see it looks like you are on a fork.
Some of the delegates you list as missing blocks have 100% participation on my end.

So that means delegates with "bad behavior" will get better statistics (reliability) than the "good" ones...
I mean when a delegate owner has enabled all delegates on 5 different servers he will probably never "miss" a block (high reliability) but create many forks... (Am I missing something?)


PS By the way I disabled my delegates on the second server
     Sorry for the inconvenience...

PS2 I was on the original main chain on both systems...  :-\

You forget that forks are known to all participants .. once we see you sign two different blocks with the same key we can un-approve you!
AFAIK that's what BM means by auto-voting/auto-kicking ... it's just not implemented yet ..

BTW. I have a second VM running which monitors my missed blocks and activates the backup if necesarry ..
current issues:
 - if I just miss 1 block the backup machine goes online and my delegates produce forks
 - if the host machine goes down (power supply) also the backup is down ... can fix this with a second dedicated/VM somewhere else once i have the time and a little money earned ..

Your second machine shouldn't monitor the missed blocks. It should monitor the running state of the main machine (is it online? is the client running?).

This is because if you are just checking the missed blocks you might still end up with both backup and the original running and signing blocks. (If the reason for missing block is for example network delay).

you could activate the backup if lost x blocks in a row (for example x=10)
Then it would be activated the most times for the right reasons... It will not be a big deal to miss 10 blocks or so if you already have produced 1000+ blocks. And your delegates will not be in risk for auto-firing because they created to many forks...

This is also wrong. You shouldn't rely on the missed blocks at all. Your backup should check the running state of the actual machine by another means. You should make sure it has stopped and/or it has no network connection at all (this might be extremely tricky).

In the scenario where you have the backup checking for missed blocks:
1 Imagine the reason for missed blocks is temporary network/hardware issue (DDOS, someone torrenting porn, switch failure, process taking too much CPU etc).
2 Imagine your backup starts producing blocks.
3 Imagine 1 is fixed (DDOS stops, porn is downloaded, switch is restarted, process finishes...)
The result will be again 2 running delegates creating forks.

this is just a temporary solution until i settled in Sweden .. gonna move tomorrow ..

I want to upgrade the backup script such that it enables all delegates, connectes to the other machine and disables all delegates again .. plus writes a mail so that I can investigate

Just a quick-and-dirty precaution to prevent what happened yesterday while I was at a funeral

The final thing will probably totally different

I just updated my script .. I need to now miss 10 or more blocks for the backup to even become active! just FYI
