Unfortunately, overnight produced the same Exception, even with the settings described.
Any other thoughts anyone?

Definitely a plan.  I put the following in my context.xml:

            validationQuery="select 1"
             testWhileIdle="true"
             timeBetweenEvictionRunsMillis="1000*60"
             removeAbandoned="true"

I set connect_timeout=5 in /etc/my.cnf, and restarted both mysql and tomcat. After 30min, everything's fine, but that's not much of test. I'll see what it looks like tomorrow morning.

Thanks,
Ken

The problem: With MySQL connect_timeout = 5, I'm getting timeout exceptions
(below)  even though I have a
validation query set; Here's my app's META-INF/context-xml:

<Context path="" debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/sb_data" auth="Container" type="javax.sql.DataSource"
         maxActive="100" maxIdle="30" maxWait="10000"

         driverClassName="com.mysql.jdbc.Driver"
         url="jdbc:mysql://localhost:3306/sb_data"
         validationQuery="select 1"/>

You might try setting testWhileIdle to true (with a reasonable value
for  timeBetweenEvictionRunsMillis) and removeAbandoned to true.

Just to see if that changes/eliminates the symptom...

FWIW,
