如何使Apache / mod_python进程收集其僵尸？

Question

Apache/2.2.6 (Unix) DAV/2 mod_python/3.2.8 Python/2.4.4 configured ...

One of apache processes spawns some long-running python script asynchronously, and apparently doesn't seem to collect its child process table entry. After that long-run-in-subprocess python script finishes - defunct python process has been left.

# ps -ef | grep httpd
root     23911     1  0 Oct15 ?        00:00:01 /usr/sbin/httpd
...
qa       23920 23911  0 Oct15 ?        00:00:00 /usr/sbin/httpd


# ps -ef | grep python
...
qa       28449 23920  0 12:38 ?        00:00:00 [python] <defunct>

What is the way to make the Apache process to collect its children? Is it possible to do the job via a mod_python request handler ( like PythonCleanupHandler for example)?

Thanks.

Answer 1

File a bug report.

EDIT: I'm serious. Leaving zombies behind is a bug, and there is almost certainly nothing you can do from within Python.

Upgrade to the latest versions, look for bug reports, post on the mailing list, switch to another product.

删除mod_python， 改为使用mod_wsgi （用于wsgi ），它不会在afaik周围留下孤立的僵尸。
