"Re: Servers swapping memory" To view the discussion, visit: https://community.jboss.org/message/795845#795845 -------------------------------------------------------------- You have totally incorrectly configured JVMs! The total memory usage of each JVM is 4 GB heap + 1.5 GB max perm (The -Xmx parameter refers to heap memory, whereas the permanent generation space is a separate memory allocation!) + other memory for threads, memory allocated through JNI, shared JVM stuff, etc. So each JVM is about 6 GB but system total memory is only 8 GB! You need to fix the allocations for the system to be stable. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/795845#795845] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2078]
