What does the ulimit command show for the userid running the server, though?  On most Linuxes, max open files is set to 1024, and this limit can not be raised by non-root users.

As said the 'ulimit' is not the problem:
Code:
$ ps -efa|grep server.py |grep -v grep
electrum 24942     1  0 06:59 ?        00:00:00 /usr/bin/python -u server.py

Do you have the open files limit set sufficiently high? 
Code:
ulimit -n
should show 16k or higher.

That shouldn't be the problem - nofile is set to 32k in the upstart script.

My setup:
Ubuntu 12.04 LTS (kernel 3.2.0) w/Python 2.7.3; latest Electrum server from git; leveldb 1.9.0; plyvel 0.8

Third time in 2 or 3 months that the database of my server e2.pdmc.net broke ("wrong_hash"). Is this just me or are other operators experiencing this as well?
Anyway, I'll take my server offline for now and bring it back online once I find enough time to move it faster hardware (probably in August).

Code:
./electrum -1 -s h.1209k.com:50002:s
wrong certificate h.1209k.com
(using plain TCP works though)

[...] I hope to release the code later this week. [...]
Oh yeah, things that don't work:
- IRC server announcement
- Most input checking on requests, requests that are wrong will most likely cause the server to break the connection with no error message to the client.
- Transactions to broadcast are handed directly to a bitcoind for validation and the response from bitcoind isn't checked so errors are not relayed back as they should be.
So, any news on this?

Your server is not good configured when I connect to him hi don't show limit of users for all servers and when I change it with another hi disappear  from the list of servers.
Hmm, I wouldn't call that "not good configured" - the server just lost its connection to IRC. After restarting it everything is back to normal.
Anyway thank you for the hint!

Is there any electrum server which updatet to bitcon core (0.9.0) and enables transactions to be propagated with 0.00001 btc fee / kb?

I've upgraded e2.pdmc.net to 0.9.1 yesterday and adjusted the minimum fee accordingly.

Bedingungen:

  • Verkauf erfolgt ausschließlich gegen Bitcoins; Escrow ist grundsätzlich möglich
  • Ernstgemeinte Angebote per PM an mich
  • Dies ist keine Auktion; es besteht kein Anspruch auf einen Verkauf.

Just in case someone is having the same trouble as me.  When I ran the foundry fulltree version from Feb I got an error saying it was deprecated.  I imagine something in the format changed.  [...]

Here's the format change which makes the foundry full tree version (from Feb 17th) unusable:
https://github.com/spesmilo/electrum-server/commit/7164e2928d341fe197b68a9966542e7be1e26709
https://github.com/spesmilo/electrum-server/commit/2a8c19f5f3bdae38e9ef89bf7515dc10a7bb1893

And there's already somebody building a 10k db. I guess you'll be better of if you just wait for his db.

Sun Fire T1000 6-core @ 1GHz
Oracle Solaris 11.1

at 24 threads each gets .06kh/s =1.44kh/s

They're $75 on ebay, 180W power consumption.

If I mine all month I can turn $10 of power into 75 cents worth of altcoins Cheesy

compiling with -O3 made this .07 per thread, for a total of 1.68Kh/s

Compiling it with SunStudio instead of GCC will give you maybe even a little more (didn't test this for an "eternity" though).
BTW, running more threads then you a have physical cores on a Niagara based systems will gain you absolutely nothing.

€400 for a board hashing 25GH? plus vat? I cannot take part then.  around 1BTC i'd pay for 25GH board, but even that is steep, as it is readily available at that price (though at higher power consumption).
25GH/s? Where did you get this number from? AFAIK the "BitBurner Fury" boards are hashing at ~50GH/s.

Whats the matter?

Either the coins you're trying to spend are too new or your choosen fee is to low.

I can't get mine to work with 1 usb cable either...  Alone they mine fine.

Anyone get multiple boards mining with 1 usb cable on windows?  Any secret?  Does your PC recognize them as separate miners, or just 1?
Did you terminate the CANBUS (properly)?
--> http://www.burninmining.com/assembly-instructions-part1/


Would anyone be interested in reasonably priced fury boards?
I would have to gather enough orders for one reel though.
In general - yes. Heavily depends on price and delivery date.

Why the delay:
CryptX has not paid me yet, that lead to me being unable to pay my contractors which then stopped production.
After a lot of back and forth i managed to convince them to finish the Job.
Cryptx didnt pay you till now... i dont see a reason why they should do this.

Uhm, what? You don't see a reason why CryptX should pay his debts? Can you elaborate?

Guess i shouldn't have gotten the power supplies from you then since they can't power your own boards =)

I guess you've should read the specs more carefully.
The Mean Well is good for 60W (http://www.burninmining.com/product/mean-well-gs60a12-p1j/), which is good enough for up to ~372MHz:

Pontius - what Avalon/Bitburner devices are you mining with?  What command line arguments are you using?

Bitburner XX

455MHz @ 32C?  Shocked Are you running them in your fridge???
Anyway I'll try with my air cooled bitburners and "--avalon-auto". Let's see what happens...
For me "--avalon-auto" results in slower hashrates - after about 10h it went down to ~320MHz (starting at 380MHz). I'll try again with v3.4.3, maybe this will result in better rates...

I would really like to see pictures of solaris setup, must look awesome.
