The latest version of Satoshis from Curse (v1.3.1) causes Craftbukkit 1.7.9 to hang after announcing that it is downloading the blockchain, in a manner somewhat like this:

[16:08:42 INFO]: [Satoshis] Enabling Satoshis v1.3
[16:08:42 INFO]: [Satoshis] Connecting to peers...
[16:08:42 INFO]: [Satoshis] Downloading Blockchain...

The server becomes entirely unresponsive to commands after this point.
