Description
Our environment is 3 nodes Galera cluster - 2 DB nodes + 1 arbitrator
one DB node hung (state "Filling schema table") when running show status command. Galera cluster encountered flow control. We can still run "show processlist" and "select * from information_schema.innodb_trx" in this DB node.
DB error log is empty
Checked one galera slave thread was running command "Busy" with state "innobase_commit_low()" in this DB node.
| 96 | system user | | | Busy | 6673 | innobase_commit_low() | NULL | 0.000 |
|
tried to kill the slave thread but command hung
We finally restart the DB node to resume
any idea what caused this issue ?
attached processlist and "select * from information_schema.innodb_trx"
