Shutdown hangs after upgrade to 10.5.12
Shutdown hangs was reported on some sites after upgrade to 10.5.12 (from 10.5.10).
This is semisync replication. Master was started and running while 2 slaves hang on shutdown (done with innodb_fast_shutdown=0)
Configuration parameters are same between those site that work and does not.
Backtraces are attached here.
I am trying to get more details, but according to initial report some nodes work without problems, while other hangs (for days).
Some of parameters are:
MemTotal: 32471016 kB(30.97G)
innodb_buffer_pool_size 4294967296 (4GB)
tmp_table_size 16777216 (16MB) <--I asked bump up to 134217728 (128MB). But it was rejected since "worked before upgrade"
