Then I did some stuff during baloo file extractor was working like testing the search in dolphin, or hovering with the mouse pointer over multiple (also large) items. I did this many times, when I get a crash the backtrace always looks like the attached one. It also happened one time just opening a directory with large files that is not indexed (like /var/crash) and hovering with the cursor over such an item.
Crashed again, now I have installed additional debug symbols though: --- stack trace --- #0 0x00007f53e2519f79 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 resultvar =

After crashing searching keywords from the file works, as long as one line is not too long. Parts of too long lines do not get found. (Talking about the crash dump file I gave the url to)
This directory triggered a few crashes: http://ubuntuone.com/5Wy0Y7AiJP60SxebOlPOhK

Download the mentioned folder http://ubuntuone.com/5Wy0Y7AiJP60SxebOlPOhK go to the folder and hover with the mouse over each file. Many baloo processes will start. Here it takes forever for them to finish, under heavy cpu load, memory usage is okay here. Sometimes baloo_file or baloo_file_extractor dies during that process.
After some heavy cpu usage I decided to kill baloo_file_extractor, see the following screenshot of top: http://ubuntuone.com/1deQlXKoGv00mn61sC42rs (The CPU usage was this high all the time) This process was triggered by the uploaded folder. I/O usage is also pretty high: http://ubuntuone.com/4d8YcKp8vWL0r200N2eNCZ (also constantly over that time frame ...)
Created attachment 86066 [details] htop showing baloo eating up the CPU. CPU at max clock freq.
Comment on attachment 86066 [details] htop showing baloo eating up the CPU. CPU at max clock freq. I'm having the same problem with CPU and IO usage. Kill $(pidof baloo_file_extractor) is of no use, it just restarts (kill -9 is the same). Sometimes it stops taking over the CPU momentarily, because it stays on D state (so it can't even be killed). It's completely lagging my tasks. Disk is working all the time. Memory usage is fine, though.
I'm marking this bug as FIXED. We didn't handle large text files very well. With 4.13.1 we now only index files with mimetype "text/plain" if they end with a ".txt". It's a temporarily solution until we can handle very large text files. Please reopen if this still occurs with 4.13.3.
