Java.io.EOFException com C3P0 e Mysql

Pessoal, estou com problemas com o pool de conexões C3PO. Minha aplicação está disponível o dia todo, porém, fica ociosa por algumas horas (+ ou - 6 horas) E, passado esse tempo ocioso, se eu tentar fazer uma consulta ao banco de dados, está acontecendo o seguinte erro:

java.io.EOFException

Estou usando MySQL 5, Hibernate + C3PO. Minhas configurações do pool:

&lt;property name="hibernate.c3p0.max_size"&gt;10&lt;/property&gt;
&lt;property name="hibernate.c3p0.min_size"&gt;2&lt;/property&gt;
&lt;property name="hibernate.c3p0.timeout"&gt;5000&lt;/property&gt;
&lt;property name="hibernate.c3p0.max_statements"&gt;10&lt;/property&gt;
&lt;property name="hibernate.c3p0.idle_test_period"&gt;3000&lt;/property&gt;
&lt;property name="hibernate.c3p0.acquire_increment"&gt;2&lt;/property&gt;

Li outros tópicos semelhantes onde falaram que isso é um bug do C3PO, sendo recomendado trocar pelo DBCP do Jakarta. Mas também disseram que o pessoal do hibernate não recomenda o uso do DBCP :shock:

Alguém sabe o que pode ser?
