عرض مصدر The service "cpanel-dovecot-solr" appears to be down

<div dir="ltr">
Cpanel Server which running Apache solr normally but sudenly suddenly gives an alter that says: <syntaxhighlight lang="text">

Service Status
failed :no_entry:

and when we check the file /var/log/messages using command `cat /var/log/messages | grep solr` we can see the following error:
<syntaxhighlight lang="text">
Jul  1 11:36:49 ServerName cpanel_dovecot_solr_firewall[3474786]: flush chain inet filter cpanel-dovecot-solr
Jul  1 11:36:49 ServerName  cpanel_dovecot_solr_firewall[3474786]: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

and IF we try to restart using '''/scripts/restartsrv_cpanel_dovecot_solr''' we got error.!!

After few investigation we found that it is a cpanel problem:

cPanel's Dovecot Solr service will update during cPanel nightly updates. During a recent update, a conflict occurred in the NFT tables rules in AlmaLinux and possibly CloudLinux 8 servers. Due to the conflict, the update cannot cleanly start Dovecot Solr because the required firewall ( NFT tables ) rules are failing to be cleared/added.

'''Cpanel Says:''' 

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-43012.  

To fix this use the following command:  (Please note that if you are using the ConfigServer Software Firewall, you must restart their service instead of NFTABLES.)  <syntaxhighlight lang="bash">
systemctl restart nftables; /scripts/restartsrv_cpanel_dovecot_solr

</syntaxhighlight>
Please note that if you are using the ConfigServer Software Firewall, you must restart their service instead of NFTABLES. so you can run <syntaxhighlight lang="bash">
csf -r; /scripts/restartsrv_cpanel_dovecot_solr 

</syntaxhighlight>
