Manual:$wgMaxShellMemory/pt-br

Padrão
102400 KB = 100 MB, 307200 KB = 300 MB, etc.

Detalhes
Under Linux, shell commands are executed with the time and memory limits given by  and. Setting either variable to 0 will disable both limits.

If generating thumbnails with ImageMagick fails with a web server error log message like "Memory allocation failed" or "/bin/ulimit4.sh: Segmentation fault /usr/bin/convert ...", the  value may need to be increased.

Se estiver usando Batik para renderizar gráficos SVG em alguns sistemas, este valor tem de ser aumentado para a extensão funcionar. (A frase "Could not create the Java virtual machine." pode aparecer no log de erros do Apache, se esse problema está ocorrendo.)
