docker-electrs's Issues

thread 'bulk_index' panicked at 'index 2497364531 out of range for slice of length 133729722', src/libcore/slice/mod.rs:2674:5

I'm running umbrel on an IBM Z (mainframe, 64-bit, big endian) running Ubuntu 20.04.2 LTS. Everything is running fine, except electrs. electrs effectively stops running (sleeps indefinitely) after the following error message:

thread 'bulk_index' panicked at 'index 2497364531 out of range for slice of length 133729722', src/libcore/slice/mod.rs:2674:5

Starting from a new node, electrs runs and waits for bitcoin to fully sync:

...
electrs | WARN - wait until IBD is over: headers=688177 blocks=688052 progress=0.9994805920510615
electrs | WARN - wait until IBD is over: headers=688177 blocks=688058 progress=0.9995014055113616
...

once bitcoin is sync'd, electrs starts building the index:

electrs | DEBUG - opening DB at "/data/db/mainnet"
electrs | TRACE - latest indexed blockhash: 0000000000000000000000000000000000000000000000000000000000000000

the following errors get logged and electrs sleeps forever after the last one:

Any ideas what might be wrong, where I can start looking for the problem? I reproduced this several times, even trying different 3 different OS's to build the electrs image.

If it proves too elusive, can run something other than electrs?

Thanks for any pointers.

Add timestamps to electrs logs

The logs from electrs don't have timestamps.

electrs should be terminated with SIGTERM

https://github.com/getumbrel/docker-electrs/blob/master/Dockerfile#L30 uses SIGINT which causes the compaction on the data to happen at every startup ... which is not great.

This should be just SIGTERM, see romanz/electrs#64 (comment)

Update Electrs to v0.10.0

Umbrel is running an older version of Electrs v0.9.14. Update Electrs to the newest version v0.10.0.
