      Description

      Hi there,

       

      since v2.229 we are experiencing Jenkins getting "slow" with ending up finally inaccessible: "read time out"

      First this behaviour happend all 1-2 days now it happens 1-3 times a day.

      • Host got 8 CPU Cores
      • Jenkins can get 3GB RAM max (it reaches 1,5 max)

      I also found out that if this happens one of the 8 CPU Cores runs at 100% permanentely - thats probably one Symptom for this behaviour.

       

      I also removed old crap & stuff and got some more defensiv Scanning times and so on.

      Nothing helps.

            heinzepreller Seems reasonable. Do you use LDAP Plugin or Active Directory Plugin (or something else entirely) for the security realm?

            This looks a lot like a duplicate of JENKINS-52374, you're right.
