Customers, particularly in the Federal Government space, have reported issues launching the ArcGIS GeoEvent Extension for Server when the McAfee Enterprise Suite has been deployed in their environment.
The McAffee Enterprise Suite offers anti-virus and malware protection. One component of the suite, the On-Access Scanner, actively scans files used and/or accessed by a running program. This has been shown prevent the proper installation and startup of the GeoEvent Extension. As highly compressed archive files (such as the JAR files utilized by the GeoEvent Extension) are scanned, access to the files is restricted, and multiple timeout failures can occur while waiting for the scans to complete.
