[error] gen_server.erl:949 Generic server ar_chunk_storage terminating. Reason: {{badmatch,{error,timeout}},[{ar_chunk_storage,handle_call,...},{gen_server,...}|...]

[ThomasBlock]

Hi Lev, thank you for your continous work here. As i use arweave more and more, i discover more and more errors. i check the old issues, but my errors seem all to be "new". are you interested in all of them? or should we accept the fact that there are problems from time to time..

This crash leaves arweave in a "half open" state - process still running but not responding to http request or doing anything else. But luckily it can be fixed with a restart.

Hi, timeouts are often temporary and recoverable, but failed_to_instantiate_rocksdb_iterator requires a restart. Could you give some more details about your setup (which disks and filesystems do you use, how many MB/s does the node download)?

[ThomasBlock]

Thank you for your fast reply! yes it recovers.. but now ten hours there is a similar error: ( LOCK: No locks available )

This node is my strongest, as i want to download the full weave. Dual EPYC CPU, 600 GB RAM, 3 TB Enterprise NVMe for data folder, ext4, Ubuntu22. only chunk_storage is symlinked to a nfs server ( HDD drives RAID6 as ext4 ).
I have 100% blocks and 34 TB weave, 10000 peers.. the download never reaches more than 40MB/s .. so i get 1-2 TB/day .. this is not much considering that the system uses sometimes 20 cores, 300 GB RAM and has a Gigabit Connection. any ideas how to increase this are highly welcome..

on the other hand i guess i should not put too much stress on the HDDs? i often see these messages which i did not see on a ssd chunk_storage:

update on this: one more error failed_to_instantiate_rocksdb_iterator / IO error: lock hold by current process
but arweave restarted itself and is now working fine again. here some logs
