求助：压力测试test_download.sh时出现的报错。

小糊涂神儿

test_download.c中相关配置如下：
#define PROCESS_COUNT   20
#define TOTAL_SECONDS   8 * 3600
static TestFileInfo files[FILE_TYPE_COUNT] = {
        {5 * 1024, "5K",         1000000 / PROCESS_COUNT, 0, 0, 0},
        {50 * 1024, "50K",       2000000 / PROCESS_COUNT, 0, 0, 0},
        {200 * 1024, "200K",      100000 / PROCESS_COUNT, 0, 0, 0},
        {1 * 1024 * 1024, "1M",     2000 / PROCESS_COUNT, 0, 0, 0},
        {10 * 1024 * 1024, "10M",    200 / PROCESS_COUNT, 0, 0, 0},
        {100 * 1024 * 1024, "100M",  100 / PROCESS_COUNT, 0, 0, 0}
};
