看起来芹菜在任务完成后不会释放内存。每完成一个任务,就会有 5m-10m 的内存泄漏。所以有成千上万的任务,很快它就会用完所有的内存。

可能与问题相同,但没有答案: RabbitMQ/Celery/Django Memory Leak?

我刚刚添加了一个测试任务,例如 test_string 是一个大字符串,它仍然存在内存泄漏:
@celery.task(ignore_result=True)
def process_crash_xml(test_string, client_ip, request_timestamp):
logger.info("%s %s" % (client_ip, request_timestamp))
test = [test_string] * 5
