php - Problems with HHVM and shell_exec -

-

i error while using shell_exec() within php script executed hhvm:

warning: unable execute '/usr/bin/svn update /daniele/myproject' in /daniele/myproject/controllers/evolution.php on line 122

the script returns warning if executed root privileges. know if there problem shell_exec() in hhvm?

thanks!

i have experienced similar issue times hhvm 2.2.0. wasn't able reproduce sudo su -s /bin/bash hhvm , gone after hhvm service restart, looks kind of leak. haven't noticed such errors (yet?) after migrating hhvm 3.1.0 few weeks ago.
