Known issues:
- If an earlier version of factomd was run, it may have corrupted your local database. If you are seeing panics as you are booting the latest factomd, the safest fix is to delete (or rename) your ~/.factom/m2/main-database folder
- On machines with 4GB or less of RAM, memory spikes have been observed which cause the OS to stop factomd while downloading the blockchain.
- This latest update fixes some consistency bugs. It is more aggressive in filling in gaps introduced when synching the blockchain with marginal network connections. This fixes some problems people were seeing with missing entries. (factoid transactions did not fall under this bug)
- This updates to Golang 1.8, which gives better garbage collection.
- Added some stabilization of the network connectivity.
- Resolve "too many files" error
On Linux and Mac, factomd would crash due to using too many open files. This bug has been solved, and factomd no longer needs the adjust the ulimit in order to work.
- Resolve Windows Database Problem
Enterprise Wallet and factom-walletd on some Windows systems would not cache factoid transactions. This solves the User Map Restriction bug.
- Networking more Resiliant
Timeouts for network connections have been increased. This gives an incremental improvement for some stalling problems that factomd nodes have been seeing.
- Lower CPU usage
Idle time CPU usage has been decreased for times after factomd boot and syncs.
- Right Click in Wallet
Now the Enterprise Wallet supports right clicking for copy/pasting etc.
factomd is much slower to start on a spinning hard drive, compared to a solid state drive. It is recommended to save the blockchain on a solid state drive.
