Which of these PHP extensions can I turn off safely? (I have memcache enabled on my IPB btw - we're using mySQL and GD2)

extension=bz2.so
extension=calendar.so
extension=ctype.so
extension=curl.so
extension=pcre.so
extension=simplexml.so
extension=spl.so
extension=dom.so
extension=filter.so
extension=gd.so
extension=hash.so
extension=iconv.so
extension=json.so
extension=mbstring.so
extension=mcrypt.so
extension=mhash.so
extension=mysql.so
extension=pdo.so
extension=pdo_sqlite.so
extension=posix.so
extension=session.so
extension=sockets.so
extension=sqlite.so
extension=sysvmsg.so
extension=sysvsem.so
extension=sysvshm.so

I got a ticket response, thought I'd share with you guys

 

Hello,

You should be able to safely turn off all except for GD, MySQL and Sockets from the list above, if you are only concerned with IPB (i.e. have no other software on the server). If you use subscription manager, you may want to leave Curl enabled as well.

Please let me know if you have any further questions or concerns. Thanks!

I asked the question btw because on LIGHTTPD FAQ, a possible solve for random Error-500s might be some useless extensions. :-) If not a total cure, it's at least another nail in the coffin for the error-500.

Thank you Zybez :D

Note phpMyAdmin requires extension=mcrypt.so
