Question Oliver Thompson · Feb 14, 2018 stream.FindAt() stops processing after certain number of characters. I have a 2GB CSP.log file that I need to investigate. I'm using a %Stream.FileCharacter() object to open the file and then using the .FindAt() to search for a particular string. I'm seeing the FindAt() stop after processing 49m characters? Here is my code: k s stream=##class(%Stream.FileCharacter).%New() d stream.LinkToFile("d:\csp.log") s x="" s i=0 s j=0 w stream.Rewind() w stream.AtEnd w stream.SizeGet() while(stream.AtEnd=0){set i=stream.FindAt(-1,"Invalid password",x)+i set j=j+1} w stream.AtEnd w i w j Which gives the following output: #Caché 0 7 0 793
