[389-users] Slapd stops processing queries or providing SSL certs

[William]

Hi,

Our slapd instance stopped responding to queries or processing queries
this morning. There are no errors in the log that aren't normal for
operation, nothing in abrt, and no apparent limits that we are hitting
up against. 

Is this a known issue, or is there a way to start investigating this?
Any tips are appreciated.
