</div>Also, I guess your are using jdk 64 bits ? Then you can use more memory then just 1.5 GB.<br></div><div>Your error message is strange. Does it work if you keep all rules but reduce the number of // sessions ?<br></div>
You should give us more info. <br></div>Cheers<br>Nicolas<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/9/16 peter.kutzner [via Drools] <span dir="ltr"><<a href="/user/SendEmail.jtp?type=node&node=4025980&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>></span><br>

Hi community
<br><br>I have actually some problems to work with my rules file (.drl).
<br>It is about 1.5Meg (~2500 rules)
<br><br>After creating multiple sessions (3 to 9; StatefulKnowledgeSessions) i get an exception.
<br><br>Usually '... java.lang.RuntimeException: cannot invoke method: update ...'
<br>or directly and '....evaluate(Unknown Source) ...) is thrown.
<br><br>After reducing the rules file size to less than 500k it works without any exceptions.
<br><br>Using:
<br>Drools 5.5
<br>Win7 X64 / 16G Ram
<br><br>Does anyone have similar problems ?
<br>Are there any known memory problems within Drools 5.5 ?
<br>Or is my rules file unusually big ?
<br><br>T.i.a.
<br>Peter
