@bobinson As per the logs you had shared, you are trying to run a PeerPlays witness node without an active Bitcoin node. Hence this is expected.

An exception has been thrown due to the absence of a Bitcoin node. This called a database desctructor, which caused memory problems.

An exception has been thrown due to the absence of a Bitcoin node. This called a database desctructor, which caused memory problems.

Yes - the memory issue should be handled without causing a segmentation fault. The expected behaviour is showing a warning message and graceful shutdown as opposed to aborting the process.

[pixelplex]

@bobinson The "graceful shutdown" has been introduced pretty much the following day. Feel free to try with the latest version.

[bobinson]

@pixelplex That sounds great. Can you share the link to the commit as well ?

[bobinson]

The Bitcoin sidechain is now implemented via SONs and this issue is invalid.
