Parity error in infinite pending block

[nullable-eth]

• Which Parity version?: 1.11.8-stable
• Which operating system?: Linux
• How installed?: docker
• Are you fully synchronized?: yes
• Which network are you connected to?: ethereum
• Did you try to restart the node?: yes

Runs fine with command line:
--auto-update none --no-download --relay-set strict --force-sealing --cache-size-db 1024 --pruning=archive --tracing=on --min-peers=100 --max-peers=200 --jsonrpc-interface all --jsonrpc-hosts all --no-ui --ws-interface=all --ws-apis=all --ws-hosts=all --tx-queue-gas off --reseal-on-txs all --tx-queue-size 1000000 --reseal-min-period=1

Gives the following error with the addition of the --infinite-pending-block option:

I tried to reproduce it.

On Parity/v1.11.8-stable-c754a02-20180725/x86_64-macos/rustc1.27.2 minimal command to crash Parity is parity --force-sealing --tracing=on --infinite-pending-block with no previous "data" (chains, keys, cache, network, etc.) present.

And I can't repeat it on current Parity-Ethereum/v2.1.0-unstable-c21c19bd6-20180814/x86_64-macos/rustc1.28.0. Will investigate it further.

[HCastano]

I believe this was fixed in #9221, which is why it is reproducible in the v1.11.8-stable release but not the v2.1.0 build you tried.

[kavu]

@HCastano Thanks! Yes, I checked fb503f5 and 77a5ce6 (from #9221) really fixed this problem. So, I guess we need to wait for #9228, or use 2.1 versions.

This fix will be backported, you should have it in the upcoming 1.11.9
