We recently upgraded our TREX from SP9 to SP15. Since then, our indexes fail. The server status lights are all green, but the files get the status: preprocessing failed.
Returncode is 14128, additional info: <b>Filter: Child process terminated (OS generated error)</b>
I tried looking for it but failed, maybe I'm in the wrong place?
Anybody else has/had this problem?
Thanks in advance!
