Hi, this bug hit us when calling ghostscript from PHP code. We are running PHP fastcgi process manager (php-fpm). It means PHP workers are not killed after the request is answered to the client and it means /etc/papersize file descriptors remains alive and the number increases with each client request.
There are some workarounds like kill PHP worker after few client requests are answered or using the ghostscript parameter "-sDEFAULTPAPERSIZE=<name>". But it would be also nice (at least to system resources) to have this bug resolved. Thank you in advance! Dusan
