This article describes known issues of Waves Node and their possible solutions.
# Simultaneously Open Files
If your Linux-based machine running Waves node also runs many other tasks, in some cases your node might crash with the following error:
Caused by: org.iq80.leveldb.DBException: IO error: /var/lib/waves/data/33837022.ldb: Too many open files
The error is caused by the operating system limit of the number of simultaneously open files.
In this case the solution is to change the default values to
65536 of the following parameters in the
* soft nofile 24000 #soft limits * hard nofile 65000 #hard limits
and also add the following line in the
then reboot your machine.
# Node Deployed in Docker Crashes After Running
If your node deployed in Docker (wavesplatform/waves-private-node:stagenet) crashes immediately after running, your Docker app might be out of memory.
Solution: Change Docker preferences, so that it can use more memory.
In your Docker desktop app navigate to Settings >> Resources >> Advanced.
Set Memory value to 4GB or more and click Apply & Restart.
