I was able to reproduce this on our test system with comment 13. This effects our LDAP system too.
We use LDAP for single sign on and with Radius for WiFi, so when it locks up people can't login to a lot of our systems and WiFi authentication stops. This happens anywhere from once a week to once a month. We have some work to do on our virtualization platform before we can update to something other than Ubuntu 18.04 LTS. I don't see lincvz's PPA anymore. . . and if my understanding is correct that would basically make LDAP static until we did upgrade. Is there a recommended way forward at this point if one stays on 18.04? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openldap in Ubuntu. https://bugs.launchpad.net/bugs/1926265 Title: slapd enter in infinite loop on sched_yield syscall Status in openldap package in Ubuntu: Fix Released Status in openldap source package in Bionic: Triaged Bug description: On a production server, sometimes slapd become unbresponsive, some threads loops in sched_yield syscall and consumme all CPU.
