----------------------------------
Summary: Lateral TCP cache goes in loop and consumes all available
resources
Key: JCS-231
URL: https://issues.apache.org/jira/browse/JCS-231
Project: Commons JCS
Issue Type: Bug
Affects Versions: jcs-3.1
Environment: Linux, Tomcat 9, Adoption JDK 11
Reporter: Andrea Vettori
Hello, we upgraded from 3.0 to 3.1 and have to go back for the following
problem.
With this LTCP configuration
{{jcs.auxiliary.LTCP=org.apache.commons.jcs3.auxiliary.lateral.socket.tcp.LateralTCPCacheFactory}}
{{jcs.auxiliary.LTCP.attributes=org.apache.commons.jcs3.auxiliary.lateral.socket.tcp.TCPLateralCacheAttributes}}
{{jcs.auxiliary.LTCP.attributes.TcpListenerPort=1120}}
{{jcs.auxiliary.LTCP.attributes.UdpDiscoveryAddr=228.5.6.8}}
{{jcs.auxiliary.LTCP.attributes.UdpDiscoveryPort=6782}}
{{jcs.auxiliary.LTCP.attributes.UdpDiscoveryEnabled=true}}
{{jcs.auxiliary.LTCP.attributes.Receive=true}}
{{jcs.auxiliary.LTCP.attributes.AllowGet=false}}
{{jcs.auxiliary.LTCP.attributes.IssueRemoveOnPut=false}}
Most of the time JCS starts with the following logs
