Description of my issue

Hi !

I have an long running issue using Piwigo (I mean I don’t remember when this started to happen), which I only try to “fix it” recently: when navigating through some albums or single picture, the server freezes ! For several minutes or more. This freeze happen time to time.

Looking at some logs through the web interface, I found something like:

[12-May-2019 17:39:32] WARNING: [pool piwigo] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 9 total children

Here a more detail log from /var/log/php7.0-fpm.log.

Does someone have an idea ?

Side question: Is it better to ask here or to open an issue on github (piwigo_ynh) ?

Hi,

I’m not a Piwigo’s user nor a dev’ but some times ago I’ve increase the swap on my Raspberry Pi.
I’m not sure at all it can solve the problem but maybe it could help :

While installing Roundcube

Hello, My Raspberry Pi still freeze sometimes and don’t respond very well because of the load. So I’ve increased the swapfile from 100 to 1024 Mo. sudo nano /etc/dphys-swapfile CONF_SWAPFILE=100 -> CONF_SWAPFILE=1024 sudo /etc/init.d/dphys-swapfile restart Source : https://www.raspberrypi.org/forums/viewtopic.php?t=46472 ppr

Thanks for your answer.
I already did this recently, and increased the swapfile to 500 Mo (by reading your post to install Roundcube, but I still prefer Rainloop ! ). But this did not change the Piwigo behavior

So, it’s off-topic and I’m not going to rot it any further but my Raspberry Pi is online for the YunoHost Team in order to test installations in a container (continuous tests for applications on an ARM architecture).
I used to have issues because of the load and after increase swap step by step, I’ve finally found 1024 seems to be a good choice.

I let the log professionals, dev’ and mainteners take a closer look at this problem.

Hi,
You can also have a look at the Piwigo forum.
In particular, this thread may help you (regarding your error message with libgomp)

Good evening,

So, I did increase to 1024, and it seems to work faster (piwigo and the whole yunohost), but it did not work.
I looked also on the Piwigo forum, following the mention thread or others, but without any luck.
I finally increase the swap to 2048 Mo, without more success (although the server is more responsive again ).

It is not a big deal because I am not using it to much, but it was a good show case when showing Yunohost to others !
