Hi,
We use Spring LDAP for LDAP connection pooling in our application. Spring
LDAP in turn uses apache commons pool API for managing its connection pool.
On testing our application for performance, we find stuck threads at our
weblogic thread dump. It appears that when the connection pool is exhausted
and request for new connection objects are not rejected by apache commons
with a NoSuchElement exception.
Please advise on the problem
*
Here is our connection pool configuration:*
/<bean id="contextSource"
class="org.springframework.ldap.pool.factory.PoolingContextSource">
<property name="contextSource" ref="contextSourceTarget" />
<property name="dirContextValidator" ref="dirContextValidator" />
<property name="testOnBorrow" value="true" />
<property name="testWhileIdle" value="true" />
<property name="maxActive" value="10" />
- <property name="whenExhaustedAction">
<ref
bean="org.apache.commons.pool.impl.GenericObjectPool.WHEN_EXHAUSTED_FAIL" />
</property>
</bean>/
*
Here is the weblogic thread dump:*
