Question

我有一个测试环境，可以使用以下命令从C代码中调用python：

ActiveRecord

运行很长时间后，每次都会出现此错误：

system("flows_parser.py ....");

输入proto_steps_common_steps_defines_pb2中的

flows_parser.py第32行 proto_steps_common_steps_defines_pb2.py第9行也是反射的导入。

我在Ubuntu 16.4上输出：sysctl -A | grep shm

Original exception was:

所以shmmax应该不是问题。有人可以帮忙吗？

感谢里卡多·布兰科！它是C代码中的描述子韭菜，与python无关。我创建了管道，完成后并没有关闭它们。我找到了韭菜描述符，并将其插入，现在可以正常工作了。

OSError：[Errno 24] python导入时打开的文件太多
