Troubleshooting Semgrep CLI
Semgrep exited with code -11 (or -9)
This can happen when Semgrep crashes, usually as a result of memory exhaustion. -11 and -9 are the POSIX signals raised to cause the crash.
Review troubleshooting steps for memory exhaustion at Semgrep scan troubleshooting: Memory usage issues.
Semgrep is too slow
Semgrep records runtimes for each file and rule. This information is displayed when you include the --time flag when running Semgrep. How you choose to interact with the --time output depends on your goals.
