<br><font size=3>As far as I know, older versions of Drools were not guaranteed
to be thread-safe, <br>
and the whole (de)serialization subsystem has been upgraded since 5.3.0.Final.<br>
Could you try a later version such as 5.5.0.Final or 5.6.0.CR1?<br>

<br><font size=2 face="sans-serif">Hi,</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
We have found that some of the drools classes are not thread
safe and hence causing the whole KB serialisation and deserialisation
issues in a highly concurrent distributed cluster.</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
The below is an example of one of the instances we have come across where
the usage of a non thread safe collection as instance
variables has caused the issue.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
Could someone look into this and advise:</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
1) If this has been reported /identified and logged somewhere as
an issue already <br>
2)If there has been any fix to problems like this in later
versions of <b> 5.3.0.Final ?.</b></font><font size=3> </font><font size=2 face="sans-serif"><br>
3)If not fixed already what is the process to initiate a fix.</font><font size=3>
