Multiple crashes and freezes prevent chain download completion

yackx commented 7 years ago

Version: `0.8.10`
OS & Version: Ubuntu 16.04LTS 4.4.0-83-generic
Node type: `geth`
Number of blocks synchronized: 3,912,371
RAM: 4Gb

I've encountered repeated crashes and sync freezes, both on my MacBook Pro and on an older GNU/Linux desktop with this 0.8.10 version. The issues are much less frequent on the MBP than on my more constrained workstation, so I'll be reporting for the latter. As a result, I haven't been able to sync after half a dozen attempts, starting from an empty chaindata. It was challenging on the MBP but it managed to get through. People around me are experiencing similar difficulties.

Wallet was launched command line to get immediate logging. Let me know if I can provide more info.

1. Freezes

The splashscreen is displayed, Downloading blocks is fast then stops. I kill the application after 10 minutes and it moves forward on restart, then maybe it freezes, maybe it crashes.

2. `Error: write EPIPE`

See error04.txt

Error: write EPIPE
    at exports._errnoException (util.js:1026:11)
    at WriteWrap.afterWrite (net.js:795:14)

3. Unable to connect to socket: timeout

4. `ECONNRESET`

Workaround: start geth on its own before the wallet with increased cache (default is 128)

$ geth --cache 512
$ ethereumwallet

This seems to work much better, although I'm not sure it's ever going to complete.

On modern machine, you may have success with these settings:

get --cache 1024 --jitvm

Moving chaindata from a HDD (even 7200rpm) to a SSD makes a difference. It is still painfully slow on this older setup but it keeps moving forward.

I am running $ ethereumwallet --version [2017-10-28 13:13:14.185] [INFO] main - 0.9.2

and I am experiencing similar problems. I keep restarting the app but could not complete the chain download, yet. Sometimes the app crashes my X server, sometimes it just stops syncing. One of the cleaner crashes (the wallet quit) was the following, which at least provided a clear error message:

Hi all,

Running Ubuntu 16.04 and am getting the same error in Ethereum Wallet:

[2018-01-23 22:04:19.018] [ERROR] Sockets/node-ipc - { Error: write EPIPE at exports._errnoException (util.js:1050:11) at WriteWrap.afterWrite [as oncomplete] (net.js:813:14) code: 'EPIPE', errno: 'EPIPE', syscall: 'write' } [2018-01-23 22:04:19.877] [ERROR] main - UNCAUGHT EXCEPTION { Error: write EPIPE at exports._errnoException (util.js:1050:11) at WriteWrap.afterWrite [as oncomplete] (net.js:813:14) code: 'EPIPE', errno: 'EPIPE', syscall: 'write' }

I've tried running geth with a higher cache as suggested but it hasn't made any improvement for me.

I'll update with any findings.

EDIT: Kept restarting the node after it failed, and running geth --fast seemed to help. Now that the node is synced everything seems to be stable.

EDIT2: Err nevermind, still crashing after ~45 minutes. EPIPE error from ethereumwallet and geth stops and simply prints Killed
