I have followings:
SELS 10.04 64 bit
Nginx nginx 0.8.20
ImageMagick version: ImageMagick 6.7.8
I wrote an image compressing module of nginx with imagemagick, but now I encounterer with an error:
1. the temp directory is filled with image magick dumpped files such as:
-rw------- 1 root root 144000000 Jul 6 22:53 magick-m7WP5dH5
-rw------- 1 root root 144000000 Jul 6 22:53 magick-mpM0JLWm
-rw------- 1 root root 144000000 Jul 16 13:48 magick-ms7YLsKl
-rw------- 1 root root 144000000 Jul 16 13:27 magick-n4Zi1ktV
2. the nginx error log are as following:
Code: Select all
2013/07/16 11:53:33 [alert] 10214#0: worker process 32133 exited on signal 6
