Despite our prior efforts, we have still been tracking (and debugging) high
memory usage in our storage engine, RocksDB. We have identified some additional
fixes and this issue has become critical as of block
186592. This block
was somewhat large and has triggered Out of Memory kills on much of the network
as it propogates out. This release contains improvements that should allow the
network to absorb past that block.
Additionally this release bumps the assume-valid block to
- RocksDB cleanups in ledger: PR: core/359
- Compact libp2p peerbook on startup: PR: libp2p/251
- Increase libp2p relay lifetimes: PR: libp2p/252
We’ll beta this release briefly starting around 9pm PST and release it to general availability ASAP thereafter.
