--light client is stuck at #2088992

see bottom half of issue 8145 comment #8145 (comment)

solution was: Wait 2 days, then try again.

what are possible reasons for the light client to get stuck for hours?

what can I do in such a situation?

what could you do to make it less likely?

thanks.

In such cases, restarting the light client would help.
This issue will be worked around with #8075

[drandreaskrueger]

Oh, misunderstanding. Of course I had restarted parity, and several times:

Yes, tried restarting.

You see that in my log cited over there in the other issue, look at the ... and the datetimes.

But restarting did not help.

What did help was waiting 2 days, and now trying again.
Synced now, thanks a lot.

[drandreaskrueger]

I have given up on that.

Instead I have now helped myself to a bootstrap file

• parity-mainchain_20180423 .zip bootstrap file

  • (might be gone, because superseded by a newer file; 50 GB max; see these instructions:

• short manual how I did that

For now, I keep a cloud machine running, so that I can always zip & download a synced chain. Download time is 3 hours - but that is better than never ever getting it synced again.

[Tbaut]

As stated before, Parity v1.11 should solve this problem.

[drandreaskrueger]

when stable?

[Tbaut]

Will go live next week as beta (light mode is experimental for 1.9 and 1.10 too).

[drandreaskrueger]

Great. Looking forward to light being stable, and incl. token balances & transfers.

Until that dream becomes reality *g* --> https://gist.github.com/drandreaskrueger/88cf4e27c69272e68d44076aaf9a8844

[drandreaskrueger]

is the token balances & transfer now working in the light client?
Thanks.
