ADFS Keep looping and showing 500 error sometimes when user accessing RRS feed

  • Question

  • Hi all,

    We are using ADFS 4.0 in our platform and we found that when user is accessing ADFS Proxy -> ADFS, sometimes it will keep looping and showing http 500 error. When user refreshing the web page, the problem gone and he/she can login again. We have checked the event log on ADFS and some event with event ID 222. Anyone also hit this problem before? Is it useful for us to fine tune the ADFS congestion setting?

    The existing setting is

    <congestionControl latencyThresholdInMSec="8000" minCongestionWindowSize="64">

    Thanks a lot for help
