Recently while working in Zend Studio I had couple of crashes that I finally traced down to it running out of memory. After searching around I found that you can bump up it’s default settings by editing it’s .ini file.
The file is located in /Applications/Zend Studio.app/Contents/MacOS
# cat ZendStudio.ini
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-showlocation
-name
Zend Studio
-vmargs
-Xms512M
-Xmx1536M
-XX:MaxPermSize=256m
-DGIT_SSL_NO_VERIFY=true
-Dsvnkit.http.sslProtocols=SSLv3
-Djava.awt.headless=true
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Xdock:icon=../Resources/mac.icns
The settings that you need to bump are Xms and Xmx (in case above they are already bumped up.
My Zend Studie has not crashed since. Happy coding!
