[mapguide-users] The roadblock for Ubuntu 14.04 support

[Jackie Ng]

Hi All,

For the longest time, the official supported version of Ubuntu for MapGuide
is Ubuntu 12.04 LTS.

The reason for this is because on 14.04 there is a blocking issue with
server stability. If you load the Sheboygan map and do several zooms and
pans, MapGuide will quickly crash with a stack trace like this:

*** Error in `/usr/local/mapguideopensource-3.1.0/server/bin/mgserver':
corrupted double-linked list: 0x00007fffa0d43e20 ***

Program received signal SIGABRT, Aborted.

I don't really have an idea why this is happening, but this is the
roadblock to MapGuide running on Ubuntu 14.04. Any help to solve this would
be appreciated.
