0010619: Game Freeze with 100% cpu usage since update to 44.06

Notes
(0037908) ArmokGoB (reporter) 2018-03-13 07:13	Is this still happening in 44.07?

(0037910) lethosor (manager) 2018-03-13 08:01	Can't reproduce this in 0.44.06 (OS X). It runs from 3/20/1324 to 3/24/1324 without issues. Note that on 3/21 it drops down to 0-1 FPS and stays there for a few minutes. Have you tried leaving it alone for a few minutes to see what happens? Also, your save is one of the largest I've ever seen, and took several minutes for DF to load. I don't believe Toady has access to a very high-end machine either, so if you could try to get a smaller save to produce the issue, that might help. Also, how did you download DF? Particularly, did you download it from a package manager? Those sometimes include a modified version of libgraphics, which is about the only Linux-specific thing I can think of (besides OS issues) that could cause a freeze at low FPS.

The save is big because I generated a 1300 years world. It's not running on a high end machine. As mentionned, it's this thing. (I like it because it's like a server, and very stable) https://www.amazon.ca/gp/product/B017YB3QSK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 [^] The low FPS you got is probably the trigger of the loop. When it does on my side, the FPS still displays its usual 6 fps, and nothing is blinking on screen.(first occurence of the issue ran frozen for almost an hour before I noticed. My DF installation is completely vanilla. Got the install from the official site. I copied my init.txt and d_init.txt from my previous version. (modified for no intro, no sound and show FPS I think.) Do they change from 1 version to another? (I have backups of the originals. )I can also try to replace them by the original.

I'm running a fort since a few months, I'm running it since 44.02 And since the 44.06 update, it randomly falls in an infinite loop after a while. Since I run full screen, I was unable to get back to my UI, and had to restart the station. It did this many times, but last time I ran it in a window instead of full screen, so I was able to access my desktop, and open htop, and take a screen shot: https://imgur.com/MJaxnAI [^] 4cores, 1 is 100% by DF Game frozen, nothing blinks on screen (when some tiles should) No activity, no response, it's frozen. Looking at htop, one of my cores is 100%, and DF takes 25% cpu. makes sense... so infinite loop... EDIT: ok. screenshot strangely doesn't show 1 cpu 100%, but it was for a long time until I took the screenshot. It went back to 100% after. DF displays 100% cpu still.

(0037914) lethosor (manager) 2018-03-13 10:13	This seems to be the same as 0010615, so I'm resolving it as a duplicate. Thanks for the useful information, though. I'll link to this report from there too.
