Yes, probably. I didn't notice this behavior before I started to use  
roundcube (webmail),
which require lots of php dynamic extensions.

From php.ini:

extension=mysql.so
extension=gettext.so
extension=gd.so
extension=iconv.so
extension=mbstring.so
extension=mcrypt.so
extension=sockets.so
extension=dom.so

(not all of these are required for roundcube)
