Re: [E] error creating connection pool
Make sure the backend DB has enough connections. DB connections total
should be the sum of all your datasurces maxActive connections plus a
couple for good luck.
To me, it appears DB is not permitting enough connections or your maxActive
in your datasource config is set to high.
<Resource

auth="Container"
url="jdbc:mysql://<FQDN>:3306/xxxxxxxx"
driverClassName="com.mysql.jdbc.Driver"
password="XXXXXXXXX"

type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1"
validationInterval="30000"
* maxActive="10"*
minIdle="10"
maxWait="10000"
initialSize="10"
jmxEnabled="true"
