Host Monitor Web Interface Fails Every 1 -2 hours

Host Monitor Web Interface Fails Every 1 -2 hours.

When attempting to log on to the web interface with a web browser, the following error is reported on the web browser:

Response from HostMonitor's web service:

Error: Cannot Read Data

Possible reasons:
- Host Monitor is not running
- RCI Interface is disabled
- HM Web Service configured incorrectly (wrong TCP port or IP address)
- Network problem


None of the above reasons are the cause of the problem.


The Host Monitor web problem is fixed by automatically running the following script every one hour:

net stop "KS Web Service"
tasklist|find /i "hostmon.exe"
if errorlevel==0 Taskkill /IM hostmon.exe /F
sleep 30
net start "KS Advanced Host Monitor"
net start "KS Web Service"

This script basically recycles the Host Monitor web service. This allow Host Monitor web interface to run reliably for an hour, perhaps up to two hours. When the Host Monitor web component is recycled, there is an outage for several minutes while the service stops and starts. Is there a way that the Web interface could run reliability?

The server is configured to run hundreds of tests per hour. Is there a practical limit to the number of tests that should be run? Is there a minimum system resources that are needed?

Could you please provide more information?
- What Windows do you use?
- Service Pack?
- HostMonitor version?
- Do you use ODBC logging or ODBC test method? If yes, what ODBC driver do you use?
- Do you have installed some antivirus monitors, personal firewall, content monitoring software? Non stanard winsock components?

Could you check resource usage for each process when this problem appears again? You may use standard Windows Task Manager to check Handles, GDI and USER objects. What is the total resource usage on the system? How many handles/threads/GDI objects used by hostmon.exe and webservice.exe processes?
