The only thing that comes to my mind is that, we tried to upgrade thought the WEB UI interface but it gave me issues so then i manually upgraded the server.
We didn't do any other updates.


I added the opcache.fast_shutdown=0 and the issue still exists.

The php version looks good.

Are you still seeing the zend_mm_heap errors and the timeout errors in the /var/log/httpd/error_log file?

In the XI GUI, go to the Admin > System Settings menu and if the hostname is used in the Program and External URL, change it to the IP address instead of the hostname.

Code: Select all

http://xxx.xxx.xxx.xxx/nagiosxi/

Update the settings and close out your browser and clear it's cache.
Then login to the XI sever using the IP address, does it respond faster?

[gdolidze]

The zend_mm_heaps seem to be gone.

We always used ip address instead of hostname.

The issues still seems to be happening.

Can you post the following files so we can view them?

Code: Select all

/etc/hosts
/etc/httpd/conf/httpd.conf
/etc/httpd/conf.d/nagiosxi.conf
/etc/httpd/conf.d/ssl.conf

Also, disable the Arcserve agent on the server and see if that helps out in the performance of the system.

One more thing, disable the fail2ban-server daemon that is running on the server and see if that helps as well.

[gdolidze]

I have stoped both arcserv and fail2ban.

Here are the files you asked for as well.

The 4th file.

turning of those agent didn't fix the issue.
It just says, Your request was not processed in a timely manner. It may still execute, as the server may be temporary busy.


We are thinking of maybe doing a migration.
Do you guys have a procedure for this.
Also does the migration copy over the service history for the graphs and charts.

[tgriep]

It looks like the Apache rewrite rule in in the /etc/httpd/conf.d/nagiosxi.conf file twice and that could be causing the issue.
Edit that file and remove one of the following sections.

Code: Select all

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule nagiosxi/api/v1/(.*)$ /usr/local/nagiosxi/html/api/v1/index.php?request=$1 [QSA,NC,L]
</IfModule>

Then restart Apache by running

Code: Select all

service httpd restart

See if that helps out on the performance.

Take a look at this KB article for the migration procedure.

The issue wasn't fixed.
still get, Your request was not processed in a timely manner. It may still execute, as the server may be temporary busy.

[tgriep]

I think the zend_heap issue may still be happening but the message is not in the log file anymore.
Can you run the following commands and post the output?

Code: Select all

grep "date.timezone" /etc/php.ini
ls -l /etc/localtime
php -r 'echo date("D M j G:i:s T Y")."\n";'
date

Also, can you post the following files so we can view them?

Code: Select all

/etc/php.ini
/var/log/httpd/error_log

Thanks.
