Demonstrates how to use the DebugLogFilePath property to get information if a Chilkat method crashes or hangs.

sftp := TChilkatSFtp.Create(Self);

// Insert this code just before the method call that crashes or hangs.
sftp.VerboseLogging := 1;
sftp.DebugLogFilePath := '/some/file/path/sftp_debug_log.txt';

// Make the call that crashes or hangs,
// for example, if the method is DownloadFileByName:

remoteFilePath := '...';
localFilePath := '...';
success := sftp.DownloadFileByName(remoteFilePath,localFilePath);

// Note: If the method returns control to your application code, then it did not crash within Chilkat.
// The DebugLogFilePath property causes all information that would be recorded in the LastErrorText to be emitted to the
// log file (with immediate file write flushing, i.e. no buffering).  Thus, in a crash situation,
// the log file will contain information up to the point of the crash.

if (success = 0) then
  begin
    Memo1.Lines.Add(sftp.LastErrorText);
    Exit;
  end;
