Hi Sergi,
I have noticed you as a very active member on the Hibernate forum. I have logged the issue which I am facing on the forum but didn’t receive any reply so was hoping that you could help me with the same.
I am using Using .NET 1.1, AndroMDA with NHibernate and MYSQL 5.0.27 as the database. I am also using the MYSQL connector 1.0.9 for Nhibernate.
This exception occurs randomly on production and everything works fine on reloading the page. We have not encountered this exception while development. Seems to be some issue with the cache or some many-to-many relationship issue
I have checked all hbm mapping files are embedded resource. we have caching enabled and settings as given below:
Caching Entries
<!-- NHibernate caching settings-->
<property name="hibernateEnableCache">true</property>
<property name="hibernateEnableAssociationsCache">false</property>
<property mame="hibernateQueryUseNamedParameters">true</property>
<property name="ehCacheEternal">false</property>
<property name="ehCacheMaxElementsInMemory">100</property>
<property name="ehCacheOverflowToDisk">false</property>
<property name="ehCacheTimeToIdleSeconds">0</property>
<property name="ehCacheTimeToLiveSeconds">172800</property>
<property name="hibernateAssociationCache">read-write</property>
<property name="hibernateEntityCache">read-write</property>
<property name="hibernateUseQueryCache">false</property>
