| Description |
|
MCS 22.08 and onwards has a new ExtentMap in-memory representation leverages RBTree over shared memory. There were certain issues with MCS 5 where the EM format was first coined, namely some undefined behavior. There is a presumption that MCS 5 suffers from the fact that all systemd units in MCS 5 restart at once when one the units(e.g. ExeMgr) fails. |
