Entries not saving CDbException We have a very strange issue here. On my computer I'm trying to save an entry. The process indicator keeps spinning for about five minutes before this exception comes up:

CDbException
CDbCommand faalde tijdens het uitvoeren van volgend SQL statement: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away. The SQL statement executed was: SELECT `locale`
FROM `craft_locales`
ORDER BY `sortOrder`

It's triggered by this function:
$this-&gt;userSession-&gt;checkPermission('accessCpWhenSystemIsOff')

On first look this definitely looks like a server issue. But... when I test this on a windows computer, it never happens. It's just not saving from an osx computer (browsers tested on osx: chrome, safari, firefox). Also tested on different osx computers and different windows computers. All with the same result. Windows works, osx doesn't.
Does anyone have a clue what might be going on here? Thanks!
I had the same issue. Tried setting a bunch of mysql and php configs for timeouts, packet sizes, etc, and nothing would help. Finally found that turning off dev mode fixed it for me. Don't know why. Just thought I'd throw that out there in case someone else was having the same problem.
