How is the disk space?

[sergmx]

/dev/sda2 29G 8,6G 19G 32% /
/dev/sda1 488M 273M 180M 61% /boot
/dev/mapper/vg1-data1 3,7T 3,5T 225G 94% /mnt/data1
/dev/mapper/vg-data 880G 724G 112G 87% /mnt/data0

i restart computer and all works.
After a while the pattern repeats.

Have a look into Apache and semaphores.

[sergmx]

I know. But I don't know what to do with it.
Here we are today:

Rebooting helps.

UPD: I restart server and view in logs:

Having looked I can see we've been here before. I don't think I can help you with this.

I suspect there i something specific to your ZM install that creates this situation. What you've posted here is a symptom rather than the problem.

[sergmx]

I understand. But it's not about installation. I use regular Сentos79 with the latest updates.
And on different computers and more powerful and weaker. With different cameras ... it comes round at different intervals.
And if I'm not mistaken it happened after another update of apache in the distribution ... (I do not remember exactly)

I can not understand, but it seems to be connected somehow with manipulations on the side of the klient through the browser. So far I can not find out.

Here's some ideas -

This just fixed it for me on v1.36.25

Code: Select all

echo 'Mutex posixsem' >>/etc/httpd/conf/httpd.conf

Thank you very much. It works in the version : zoneminder-1.36.33-1.el7.x86_64
