This may have been a corrupt transactionpool.db, but even if that's true, it doesn't seem like panic is the right behavior. Should these dbs get checksums?

tbenz9 commented 6 years ago

This is likely related to issue #2318 which the Devs are aware of and planning on fixing eventually. Since the error messages are slightly different let's keep this issue open and tag it as Bug.

Recommendation to Devs: "Bug"

lax20attack commented 6 years ago

Any workaround?


A critical error loading Sia has occured: Siad unexpectedly exited. Error log: Loading...
(0/6) Loading siad...
(1/6) Loading gateway...
(2/6) Loading consensus...
(3/6) Loading transaction pool...
panic: page 294241 already freed

@lax20attack unfortunately we don't currently have a workaround for this, other than ensuring you have enough free disk space and redownloading the blockchain.

Fixed on Mac by removing this file: /Users/Username/Library/Application Support/Sia-UI/sia/transactionpool/transactionpool.db
