HTTP 500.100 - Internal Server Error - ASP error

ASP Error Info:

/en/includes/systemMain.asp, line 243

Browser:

Page:

GET /Default.asp

Not able to log into GMS

Resolution

Cause 1:
This problem can happen on servers that have more than 2Gb of RAM installed. Two of the GMS Java processes (EA and Mobile Gateway) calculate their max heap size by dividing the max memory by 4. When there is more than 2Gb of RAM this results in a heap size that is too large.
Override the EA Max Heap Size by setting a registry setting on the GMS server:

DWORD - HKLM\\SOFTWARE\\Synchrologic\\Portal\\Manager - maxHeapSize value
Set a value of 536870912, which equates to 512Mb.

Override the Max Heap Size for Mobile Gateway by editing (installdir)\commsvr\conf\service.properties, and add a line that says maxHeapSize = 536870912
Restart the GMS services and retry

Cause 2:
This error can also be related to the McAfee Virus Software installed on the GMS server. It is a requirement to have Buffer Overflow Protection disabled on any GMS server.
Also make sure that none of the GMS directories or ports are being scanned with any virus software.

Cause 3:
This error can also appear when trying to log in to the webPIM (log in page would show up), if communication with the database is broken

Cause 4:
It can also occur if the Application Pools are not correctly configured, though this is the least likely scenario.
