yangwei updated ARTEMIS-1891:
-----------------------------
Description: After sending pages, the thread will hold the storage manager
write lock and send synchronization finished packet(use the parent thread pool)
to the backup node. At the same time, thread pool is full bcs they are waiting
for the storage manager read lock to write the page or journal, leading to
replication starting failure. Here we use io executor to send replicate packet
to fix thread pool starvation problem. (was: After sending pages, the thread
