Just to add only one rebuilder will start to run with the current time setting in php.ini(rebuild private messages) 30 sec.
But still fails
That seems to be the culprit.
The other rebuilders fail at onset but don't produce the same issue with closing the board..
when it is run it does not appear in the log that it was started.
Nor does it appear that the board was closed in the log.
So hopefully once the host can resolve this time issue.
it will resolve itself.
