Goal

Very high number of  instances of httpd process after tuning MaxSpareThreads to be the same value as MinSpareThreads in the mpm_worker_module

After adjusting OHS to the following settings, a large number of  httpd processes are running:


  ServerLimit 128
  StartServers 32
  MinSpareThreads 1024
  MaxSpareThreads 1024
  ThreadLimit 72
  ThreadsPerChild 32
  MaxClients 4096
  MaxRequestsPerChild 10000
  AcceptMutex fcntl
  LockFile "${ORACLE_INSTANCE}/diagnostics/logs/${COMPONENT_TYPE}/${COMPONENT_NAME}/http_lock"

Previous settings where the issue was not present

  ServerLimit 128
  StartServers 32
  MinSpareThreads 1024
  MaxSpareThreads 2048
  ThreadLimit 72
  ThreadsPerChild 32
  MaxClients 4096
  MaxRequestsPerChild 10000
  AcceptMutex fcntl
  LockFile "${ORACLE_INSTANCE}/diagnostics/logs/${COMPONENT_TYPE}/${COMPONENT_NAME}/http_lock"


Is it acceptable to set the MinSpareThreads and MaxSpareThreads to the same value?
