systemctl status nginx

Please post the output from:

Hi Frank,

I guess this is easier to read....

I will try now to use a micro SD Card with Raspi Adapter
instead a normal SD-Card

This solved a mysterious sometimes not working problem
I had with my fhem home automatiion Raspberry half year ago

I think that this problem is solved now
I have been running the server for at least 2 days without accessing
the UI for 8h+ through a browser. It didn't freeze again

So the problem probably was the SD Card or a bad contact of its pins.
Maybe rune was trying to write to the log or whatever and
couldn't perform the write process.

Any suggestions what to do ? Webradio was playing and continued to play after rune UI has frozen

Hi Ralf,

it's hard to help you.

Your problems have nothing to do with wifi.
The error is self explaining (Too many open files).
The question is, why.

On a stock system without any changes and used as supposed by the developers this will not happen.

- Did you change nginx.conf to support httpd?
- Is FHEM calling rune continously?
- updates installed?
- ?????

Well after reading that log it's obvious that it is a server problem
and not a wifi problem. I didn't know that when I sent the first posting.

- I didn't change nginx.conf.
-Rune works in http not https I was not able to set this up and
installed everything from scratch
- fhem calls rune once a minute
- I installed the file from http://www.runeaudio.com/download/
- no further changes,exept
a) in footer.php I set
<!-- loader -->
<div id="loader" style="display: none"></div> and
b) in header.php I created a link to FHEM and
c) I disabled power saving of the Edimax WLAN Dongle

So this is (almost) a stock system without any changes.
I didn't touch anything else, really ! I wouldn't even dare
as my linux knowledge is very limited....

I googled a bit......and installed and run LSOF to find out why.

I get a list of open files. See file attached. This list increases steadily.

When I enter
cat /proc/sys/fs/file-nr I get
659 0 48521
where the first number also steadily increases,
while writing this post this increased to
cat /proc/sys/fs/file-nr
719 0 48521


I don't know which files should be opened, how many usually should be
opened, if 48521 is the maximum allowed number which causes
nginx to stop working, etc.

But maybe this information is useful to you for locating the culprit...

Ralf

PS : After 2 hours lsof results in many lines (files ?) which look like that:
nginx 144 root 474u IPv4 81725 0t0 TCP musicbox.fritz.box:http->Wohnzimmer--Tablet.fritz.box:38774 (CLOSE_WAIT)

See 2nd zip. Is that normal ?
