Known Issue V19+: 'Too many open files'
-
Issue: The following error, or a similar one, can be seen when attempting to run a full node on some versions of macOS, Linux and possibly other operating systems. This is most common when using the built-in Qt wallet or other GUI-based wallets: "Exception while running wallet: open: Too many open files" or other errors containing "Too many open files". This is due to some systems having a very low default file descriptor limit and V19.0+ uses more of them after the move to TCP.
-
Solution: Increasing the file limits is needed to resolve this. See this known issue for more details on resolution.
Known Issue V20: Peers stake reporting inaccurate (Windows only)
-
Issue: For Windows builds only, when calling confirmation_quorum RPC the
peers_stake_totalamount returned may be inaccurate, returning a range from the correct full peer stake amount down to 0. -
Solution: A solution to the issue has been found and as this is a reporting issue only, the fix will be included in the next released version. For those manually building the node, patching the fix pull request onto the V20.0 tag can resolve the issue now. Or alternatively, building on the V20.0 tag with
RelWithDebInfooption, see Build Instructions for Windows.
