    2025=== Cooling issues ===
    21  * pump failures for JSC cooling loop have been detected
    22  * root cause still to be idedtified
    23  * considering manual mode to allow for operation of CM and ESB nodes in the meantime
     26 * pump in JSC cooling loop is running in manual mode: frequently running HPL jobs (with low priority) to create some load (waste heat)
     27   * HPL jobs can be killed on demand: in case of problems (your jobs being blocked by HPL runs), please contact j.kreutz@fz-juelich.de or niessen@par-tec.com
