Optimize OWASP ZAP for Large Site Scans: Preventing Crashes
Experiencing crashes with OWASP ZAP (Zed Attack Proxy) during scans of large websites is a known issue, often related to memory limitations and the extensive data processing required for such tasks. To mitigate these problems, consider the following strategies:
Increase Java Heap Memory Allocation:
ZAP operates on the Java Virtual Machine (JVM), which has a default memory allocation that may be insufficient for scanning large sites.
Click on the settings gear, select JVM, enter the proper option for the memory size value. For instance, to assign 6 GB enter -Xmx6g. (where 6 represents how much memory to allocate).
