Hello, Since I had no feedback on this problem, should I guess that the issue has been tackled in latest version? Would it be related to ITS 6892 (http://www.openldap.org/its/index.cgi/Software%20Bugs?id=6892)? I would like to know if I should upgrade consumers to 2.4.27/28 with a high priority or not! Please advise.
You've provided zero information on why they are freezing (i.e., a backtrace with debugging symbols enabled on the servers where slapd has "frozen"). Of course, I would suggest (attempting) to reproduce the issue with the latest version, as there were numerous fixes related to syncrepl & syncprov in 2.4.27/28. I personally would advise against mixing versions, also. Make all servers run the same OpenLDAP version.
