Could not save application settings error

Hello Stephen,

The "mapping failed" exception appears when you set the -Xmx to an overly
large value, and IDEA runs out of virtual address space for mapping memory-mapped
files. It can be fixed by reducing the -Xmx value or by running IDEA under
a 64-bit JDK.

After IJ auto-indexes a moderately sized codebase - maybe 250K lines
- i'm seeing following error.  I'm not sure this has to do directly
with the indexing, but seems likely the memory requirements have an
effect.

thx for the reply Dmitry.  I'm running under 64-bit windows 2003 server.      here are the settings (very conservative actually).   Note this machine has 12GB physical ram and hundreds gb's free disk space

C:\ij10\bin>cat idea.exe.vmoptions
-Xms768m
-Xmx1024m
-XX:MaxPermSize=392m
-ea

You are running under 32-bit JVM and hit 2GB address space limit for 32-bit processes. Lower heap size to 500-700m or run IDEA under 64-bit JDK: ftp://ftp.intellij.net/pub/.idea/idea64.zip.

Hello Stephen,

The amount of physical RAM doesn't matter - the virtual address space for
a 32-bit Java application is just 4G. On such a configuration, I'd recommend
running under a 64-bit JDK.
