2.0.3 linux client on production stuck at block 706973

Development Issue reports
#1

I saw a similar problem in the 2.1.0 test thread.

Sorry if this is the wrong place for this, I’m new to nubits.

Anyhow, my linux client version v2.0.3-beta gets stuck at block 706973. Seems proof of stake doesn’t check out. I did a -rescan earlier, not sure if related.

Here’s the tail of debug.log

any help appreciated

#2

Did you download the binary from the website or did you compile it yourself from source?

#3

used a binary called nu-2.0.3-linux-gitian.zip
download date: dec 20th 2015
with sha256 547fc816c06b596a449590f5307cf3b74f6fb47018f0c1cd56fce8891695ce7d

#4

so, I deleted (still have it backed up, though) the blockchain data and am resyncing with the same client. Let’s see how it goes.

#5

Did you add nodes to nu.conf?
If not, you may try again with these (after having deleted addr.dat):

#6

blockchain reload solved it, so I can’t try your suggestion, masterOfDisaster. I don’t think I had trouble connecting (posted log says “receiving block”. Question remains: who was I connected to?

thanks for your help anyway!

#7

My client is stuck on block 51140, mac app, version 2.0.3.

Tried searching for nu.conf in library but nothing. Do I need to modify a similar file?

Thanks!

#8

Did you try restarting the Nu application? sometimes that helps.
nu.conf doesn’t exist by default. If you need it, you have to create it.

#9

I have shut it down and restarted it probably 8-10 times.

#10

If I need to create it, where do I put it? The nushares program will recognize it automatically?

#11

I’m not familiar with MacOS.
I think the place where Nu stores the application data (e.g. blockchain files, wallet files) is
~/Library/Application Support/Nu

#12

ok, got it, but not sure what to do from here.

#13

Close the Nu application, add the nodes from


to nu.conf, start the Nu application.

If that doesn’t help getting you past block 51140 investigating debug.log might give a hint about what’s wrong.

#14

I think my resolution is to delete the program and start over. Thanks Mod.

#15

i have shared the version of nu-qt that contains many performance fixes that worked for me to sync everything from the start, see if that works for you:
