Issue/Introduction
The Exchange scanner stops sending idx files to the Discover server
Error: In the scanner0.log, there will be the following error:
SEVERE: Runtime Exception occurred. Restart the Scanner.Java heap spaceResolution
1) In the bin folder of the scanner (\Program Files\ExchangeScanner\bin), create two files:
ExchangeScanner_Console.exe.vmoptions
ExchangeScanner_Service.exe.vmoptions
Make sure the name of the vmoptions file is the same as the scanner exe.
2) Add the following to the vmoptions file: NOTE: these entries are case sensitive.
-Xmx1024m
3) Run the scanner either as a console or service
Note: We are assuming the machine on which the scanner runs has at least 2 GB RAM.
If the problem persists, then add the following to the vmoptions file:
-XX:-HeapDumpOnOutOfMemoryError
This will create a heap dump file in the scanner jre/bin directory, if another out of memory exception occurs. The heap dump file will have an extension of .hprof. Please send to support the hprof file if an OOM occurs again. It will be a big file (1GB at least).
Note: This solution applies to all scanners
