MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_Part_2435_15824135.1208516410069" X-Virus-Checked: Checked by ClamAV on apache.org ------=_Part_2435_15824135.1208516410069 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline We are currently running two instances of tomcat on our systems. One is for a vendor specific application and the other is for in-house written applications. We are careful to make sure the ports do not conflict and there are plenty of resources to support both; memory and CPU. Recently the statement has been made that the two instances can conflict with each other and cause issues and instability with the applications. Is this true? I was under the impression that since they are in their own JVM's neither tomcat would have any affect on the other. If there are issues in what form may they take place? ------=_Part_2435_15824135.1208516410069--
