This error indicates that at least one of the BizTalk server processes in the affected computer is being throttled for significant periods because of high process memory.
Monitoring of the "BizTalk:Message Agent\High process memory" counter over a series of samples has indicated that the threshold defined has been consistently exceeded over that period of time.
This monitor watches the value of the "BizTalk:Message Agent\High process memory" counter for all host instances. That counter has a value of "1" or "0" based on whether the thresholds have been meet/exceeded or not (respectively). If the average value over 30 samples exceeds the preset threshold, which is set to 0.6 by default, then the state will change from healthy to critical. This monitor is configured by default to generate an alert when the state is changed to critical.
The memory consumption of the process has exceeded the preset limit. If the limit is specified as a percent of available memory, this could be due to a small page-file size, inadequate physical memory, some other program on the same machine taking a lot of memory, or a combination of all.
Verify that the process memory limit is not dwarfed by a small page-file or due to competing memory-intensive applications on the same machine.
Verify that the custom components (if any) have no leaks.
Verify if the process has a higher memory footprint. If so, increase the memory limit carefully and manually tune.
