I got a problem while running the rebuildSearchIndex.php script on my OCS 2.3.5 under PHP 5.2.17.
Our OCS actually hosts 22 conferences and about 2000 papers. The script is probably not running properly due to server memory limits (I've already changed max_execution_time, max_input_time and memory_limit) but server still returns the 'broken pipe' error.
Reading upon the threads, I found your comment on Bugzilla
about executing the command for a specific journal. Hence, I ask you if is it possible to run the command for a specific Conference? regarding our OCS case.
ps: sorry for cross-posting on Bugzilla.
