nginx from macports causes 'kernel[0]: proc: table is full'

[daniel.plainv@…]

Since I installed nginx from macports, I have sometimes this issue:

and system becomes unusable: I can't run any new application including Terminal and proc table remains full.

I'm not sure, but it seems like nginx port is bugged.

By the way, is it OK that logs of nginx weren't removed after uninstalling port?

hellyeah:~ xxx$ ls -la /var/log/nginx/
total 0
drwxr-xr-x   4 root  wheel   136 25 ноя 05:17 .
drwxr-xr-x  67 root  wheel  2278  3 дек 23:52 ..
-rw-r--r--   1 root  wheel     0 25 ноя 05:17 access.log
-rw-r--r--   1 root  wheel     0 25 ноя 05:17 error.log

Yes, it is normal that logs and configuration files are not removed when uninstalling a port. Such files contain potentially irreplaceable information so it should be up to the user to delete them if and when desired.

I cannot reproduce your problem. Which variants did you use when installing nginx? Can you provide your nginx.conf?

[daniel.plainv@…]

Where are nginx logs? /etc/nginx/ doesn't exist. I'm not sure, but probably I didn't even create such dir because I didn't use nginx on that moment.

Well, I'll install this port later again and where should I look if I face with such issue?

Where are nginx logs? /etc/nginx/ doesn't exist

Argh, for sure I meant config.

[neverpanic (Clemens Lang)]

The configuration files are in /opt/local/etc/nginx, if your prefix is /opt/local. The MacPorts nginx package does not install a configuration file, but only an example of it. You need to copy the example configuration file and adjust it. Since you apparently never did this, all the nginx port does when started is print an error message and exit. If you started nginx using sudo port load nginx you would get a log message every 30 seconds telling you that launchd couldn't start nginx (which is what you saw).

However, this should not fill the kernel process table, because at any given time, at most a daemondo process and a zombie process of what used to be an nginx process are around. As soon as daemondo exits, launchd should have cleaned up the zombie. If this didn't happen in your case, it would explain the problem.

Anyway, create a working nginx configuration before starting it. I have added a message detailing this in r100667.
