Hi, I went a bit down the rabbit hole Sergio mentioned and found the same old reports and nothing really useful. I'd also be curios to see if the problem still occurs with the newer releases.
Did you see this happen on more that one machine/deployment? The backtrace didn't suggest my anything, but maybe Sergio will have better use for it. -- 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: New Bug description: On a production server, sometimes slapd become unbresponsive, some threads loops in sched_yield syscall and consumme all CPU.
