It's at 64-bit system/JVM. The process limits from /proc/pid/limits are: Max processes 16341 16341 processes Max open files 65536 65536 files
The JVM flags used are : -Xmx8g -Xss1024m The default value in JVM is: amq...@stokes31.toa(nyc):~> java -XX:+PrintFlagsFinal -version | grep ThreadStackSize intx ThreadStackSize = 1024 {pd product} java version "1.8.0_60" Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode) The OS limits and heap sizes seem more that enough to me. I have another instance that runs with same configuration and hasn't exhibited this behavior. What other factors should i look at for more information next time this issue occurs. How can i increase the native memory space if thats what is causing this? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
