AppScan Standard 8.5 or older results in "reached its predefined memory limit"
Upon reaching its memory limit, IBM Rational AppScan Standard (version 8.5 or older) stops and displays the following message "AppScan has reached its predefined memory limit".
AppScan Standard stops due to increased memory usage.
Diagnosing the problem
If you continue scanning AppScan Standard *may* crash and lose all the data.
Resolving the problem
Note: This technote describes a workaround that can be applied in AppScan Standard version 8.5 or older. For a resolution in later versions of AppScan Standard refer to technote Scanning results in error "memory exceeded a predefined limit".
To prevent AppScan from stopping due to excessive memory usage, you can set up AppScan to restart automatically when memory usage becomes too high.
When the scan ends due to low virtual memory, AppScan checks if it was configured in the registry to be restarted.
Set Tools > Options > Advanced > PerformanceMonitor.RestartOnOutOfMemory, to True if you want to turn this on.
Also, set Tools > Options > Advanced > PerformanceMonitor.MinScanTimeDurationForRestart to the number of minutes AppScan should have run before it reached the memory problem.
After seting RestartOnOutOfMemory to true, AppScan will now perform as follows:
- Compare it to its current run, this is the number of minutes the Rational AppScan instance ran, not the overall scan time.
- Check if the scan has a name, and saves it.
- Check if the users last action was fullscan/explore/test.
- Start a new Rational AppScan session while loading the saved scan and resume the user's last action.
- Close the instance of Rational AppScan that consumed to much memory.
Ensure in both versions that 'Automatically save during scan' option is enabled under Scan Monitoring in Tools > Options > Scan Options tab.
