Hi All,

I am using Hibernate3 + Oracle.
In my hibernate.cfg.xml, i have these pool configurations. Its working fine till yesterday.

<!-- configuration pool via c3p0-->
<property name="c3p0.acquire_increment">3</property>
<property name="c3p0.idle_test_period">900</property>
<property name="c3p0.max_size">50</property>
<property name="c3p0.min_size">5</property>
<property name="c3p0.timeout">3600</property>
From today whenever i am restarting the apache tomcat server 5.0, i got this exception,

If i comment these pool configs, i don't get this exception.
Its in linux enviornment.

In windows enviornement i never get this exception.

Thank you,

Siva

Please post the whole file as you use it in the linux environment

I allready had a similar problem when I tried to use Linux and got the source
through SVN.

Hi,

I got this source from cvs using ant. Now i commented the connection
pool.
