For long running processes that periodically re-initialize the library (Firefox's plugin-container loading the VLC plugin for me), this leads to the available file descriptors being exhausted. This also causes https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1177684. [test case] Fresh and clean Ubuntu Precise 12.04.2 install # apt-get install apache2-mpm-itk libapache2-mod-php5 php5-gd Restart Apache to ensure gd.so is loaded # for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}' # apache2ctl graceful # for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}' # apache2ctl graceful # for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}' .. etc [regression potential] This affects patch designed for ARM. Although all it does it properly close the file descriptor, I have not specifically tested it on ARM.
