TS-3486: Crashes due to race condition on server sessions moving betwâ¦
â¦een threads.
Addressing crash issues disucssed in TS-3266 and TS-3486. This fix has
been running on Y! 5.3.x on one production machine for over a day and on three
other production machines for several hours.
There is a race condition when server sessions reused from a global pool
are moved between threads. This patch addresses the issue by holding both the
session pool lock and the activating state machine lock while setting up the
first read.vio on the reactivated server. This prevents conflicting IO using
one lock or the other on another thread.
