+Thanks  Col. I saw one was upgraded after php TS was built, but it's now solved. I guess you rebuilt 
+some and umeabot took care of the rest. There are currently no errors using php -v
+
+When I built the TS version, I was aware something may happen and I may had to go back.
+The problem is now, 389-ds needs apache running with worker which in turn needs php TS
+
+Fedora builds both modules, TS and NTS and loads them depending on mpm-worker or not.
