    GC Overhead on ColdFusion 11

    xfreeman89x Level 1

      Hi all,

      I recently got many occurrences of this error on one of my AWS ColdFusion servers:

      "Error","ajp-bio-8014-exec-138","02/19/16","08:45:25",,"GC overhead limit exceeded The specific sequence of files included or processed is: xxxxxxxxx.cfm'' "

      where xxxxxxxxx.cfm are different files. I noticed this when CPU usage was high and expecially when my sites where damnly slow. Now I restarted ColdFusion Server but I would like to know what was the problem and how to resolve it.

      My actual configuration is:


      Ubuntu Server 64-bit 2vCPU 8 GB RAM with ColdFusion 11 update 7

      Minimum JVM Heap Size: 4096 MB

      Maximum JVM Heap Size: 4096 MB


      -server -XX:MetaspaceSize=312m -XX:MaxMetaspaceSize=512m -XX:ReservedCodeCacheSize=240m -XX:CompressedClassSpaceSize=1g -XX:+UseParallelGC -Xbatch -Dcoldfusion.home={application.home} -Djava.security.egd=/dev/urandom -Duser.language=en -Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true -Dcoldfusion.jsafe.defaultalgo=FIPS186Random -Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.JavaUtilLog


      Thanks a lot for your help.
