openHAB on Pi3 stops working and logs show Exception: Too many open files #445

Closed ghost closed 1 year ago

ghost commented 7 years ago

Hello!

I'm running openHAB 2 (stable) on a Raspberry Pi3, and from time to time the system becomes unreachable (neither WebUI, nor ImperiHome, nor SSH work) and the logs show the following exception:

2017-04-14 07:52:24.107 [WARN ] [eclipse.jetty.server.ServerConnector] -

I have to unplug the power source and re-power the Pi to get openHAB up and running again. Seems that in the code things are not closed properly!?

jwarcd commented 7 years ago

I have the same problem on a Pi2.

ThomDietrich commented 7 years ago

Did you already discuss this problem in the community forum? As this doesn't happen to the broad user base, I'd suspect this to be related to special setup/environment aspects or one binding. Before we can tackle the issue, you need to figure out what's the provoking factor.

ghost commented 7 years ago

I tired some more investigation. It seems actually related to the fact that I have quite some Image items in my sitemap, including ip camera jpegs from Zoneminder. The Image items seem to draw a lot of resources when refreshing every 2 seconds.

I also notice, that the Basic UI is getting slower and slower (and often gets stuck until a full reload).

Does it happen to you as well, that the Basic UI gets slower or unresponsive?

jwarcd commented 7 years ago

I don't use image items in my sitemap. I took a look at the open files on my raspberry pi running the latest openhab2 and saw many thousands of open files after running for a couple of days. Here is a portion of the output of the "lsof" command:

did you try to raise the limit on java user?

  1. Edit as root /etc/security/limits.conf

  2. Add the new limit of files (nofiles) to the java user:

#*               soft    core            0
#root            hard    core            100000
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#ftp             -       chroot          /ftp
#@student        -       maxlogins       4
java            hard    nofiles         65536

  1. Reboot rasp.

  2. To confirm: sudo -u java ulimit -a

It must show the new limit...

Probably you have to many items, images, calls or crons that increase too much the cache files... I'm guessing though. Maybe 65536 files are enough to avoid the file blocking.

I have increased the nofiles limit and haven't had my Raspberry Pi hasn't had a hang in over a month. I checked the number of files in use today using:

sudo -u openhab lsof | wc -l

and it shows over 62K handles in use by OpenHab. It increases to this level shortly after starting OH and stays around this number while running. I don't have that many items or images. I do use the caching with the HTTP binding to poll a single URL every 10 seconds. My OpenHab setup is not that complicated so I don't know why it is using so many handles.

Command
sudo lsof | grep openhab | sort -n | uniq -c

on my Rasp shows the same:

With a sum of:

[15:55:34] Kanashii@kokoro:~$ sudo lsof | grep openhab | wc -l
61173

So seems openhab on Rasp requires of 61173 o maybe some more depending on the osgi modules loaded to run.

Maybe the fix is so simple as raise the openhab user open file limit to "65536" on the limits.conf. Can anyone set it on the default OpenHabian image ?

If you're not using the OpenHabian image then it must be explained (raise limits) on the installation process.

shoeper commented 7 years ago

Keeping in mind the values you told I'd double the maximum.

pirndi commented 7 years ago

Have the same issuse. i only have the problem with open visu (Basic UI, Habpanel) on my Wall Tablet. after closing i have no problem so far. with tablet on i only works one day

BClark09 commented 7 years ago

Hi all,

I'm currently refactoring the systemd service file for the automatic installs (which includes openHABian). Can someone experiencing this issue (@pirndi, @jwarcd) try adding the following line underneath restart-on=failure to /usr/lib/systemd/system/openhab2.service

LimitNOFILE=102642

Other changes mentioned in this thread should be set back to default to test if the above line actually does anything.

Theonator commented 6 years ago

Same problem here on a Raspi3. LimitNOFILE=102642 makes it only worse -> 30min after reboot: RAM usage up to 100%, SWAP usage

sudo lsof | grep openhab | wc -l

shows:

1290522

JuergenBluemer commented 6 years ago

Please have a look at the discussion here:

https://community.openhab.org/t/java-io-ioexception-too-many-open-files/28204/39

I've performed several tests with PiZeroW and Pi3

My conclusion: The browser client opens in case of a manual user refresh lots of connections to the chart service of openhab.

ghost commented 5 years ago

Dear all, I have the same issues. I use BasicUI. I have my webpage always loaded on my touchpanel... I can see the increment of the number of : lsof -p PID | wc -l And when this number is too big, my openhab call an error: too many file open... I have to restart my openhab to clean memory. Do you have a solution ? Restart macOS each day ? Use ClassicUI ?

wborn commented 1 year ago

Let's assume this issue has been fixed by now.
