Warnings

Please expect a one-time delay when starting 0.31.0 while certain database indices are being built or rebuilt. The delay can be up to five minutes, during which CPU will spike and the server will appear unresponsive (no response to RPC, etc.).

Additionally, rippled 0.31.0 now checks at start-up time that it has sufficient open file descriptors available, and shuts down with an error message if it does not. Previous versions of rippled could run out of file descriptors unexpectedly during operation. If you get a file-descriptor error message, increase the number of file descriptors available to rippled (for example, editing /etc/security/limits.conf) and restart.
