I just upgraded some servers to RHEL7 and saw some really, really bad performance and
found ssse_pac to be the badguy. After disabling PAC, the system worked well. Before that,
server had a load at 200 with only 3-400 users. This is with sssd 1.11.2. After removing
pac, it was down to a calm load of 1.2 or so, similar to that of Samba 3 with winbind. Any
ideas what might have cause this?
Do you have any log files from the pac responder? Are you using the PAC
responder with IPA or AD provider? Did you see multiple sssd_pac
processes in the process list or just one?
Not sure which logs to look for. I only saw one sssd_pac process, and that had used a
helluva lot of time.
