Overlapped I/O operation error in ipMonitor

Updated October 1, 2018

Overview

When you run monitors in ipMonitor, the monitors fail with the following error message:

Overlapped I/O operation is in progress.

Environment

All ipMonitor versions

Cause

The Windows APIs used for monitoring over WMI is running threads that are trying to use a disk or socket handle that is already in use by another thread. This issue cannot be controlled by ipMonitor.

The Monitors that typically use WMI are resource-based monitors (such as CPU, Memory, Drive Space and Services) and Windows Event Log.

Workaround

 Use SNMP, instead of WMI whenever possible or move ipMonitor to a Windows or Windows Server 2008 system so its APIs can better handle overlapped I/Os that are in progress.
