Cpanel Domain ownership in cpanel will look to permissions on /etc/valiases/domain.com in some cases. Wrong ownership on this file may make the domain appear to be owned by another user.
Directadmin rewrite_confs is extremely slow. To just run a single rebuild of a user user /admin/res httpd username
Directadmin can be debugged with systemctl stop directadmin; /usr/local/directadmin/directadmin b2000
Webuzo uses epel rpm repo for exim. If exim can not install check this repo is active
kvm systems may have queue runner hang if there is a screen called backup created
zfs if file system is extremely slow check if the disk space is over 96%. This is for a USER dataset as well.
Openlitespeed and wp-rocket are not compatible and will result in a file download https://github.com/wp-media/wp-rocket/issues/2409
Storage directadmin systems do not have dns servers built in. Use cdns1/cdns2/cdns3
kvm and openvz vps can use /etc/backup.conf on the hostnode with the vps id in the format of xxxxxx to run weekly auto backups into swift
kswapd0 may use a lot of CPU if ram is low but also is commonly a hidden malware process. A real kswapd0 command is a kernelthread not a file being run
ksoftirqd high CPU may indicate a flood/dosttack or other high network activity
out of space errors could be also caused by inodes full. Check df -i or quota -u username if df does not report out of space
QVO model drives will randomly go slow. If any are detected they must be replaced.
If letsencrypt is ratelimited try the alternative zerossl provider
503 errors can be due to inode limit reached, cpu/mem reached or imunify360 more info in wiki under 503 errors
to check an ip blacklist status use https://mxtoolbox.com/blacklists.aspx
firewalld may default to blocking incomming connections. On cpanel/WHM systems replace with csf firewall
csf firewall is unreliable on virtuozzo7 systems and may fail to start
csf firewall can use CC_DENY to block countries like CN,RU and also can use country level blocks on a single port. check /etc/csf/csf.conf
on kvm pmsuspended is not a virsh suspend call but a power management suspend from the os itself - to wake up call virsh dompmwakeup vpsXXX
ipv6 local address start with fe80 where as of this writing publically accessible ipvs start with 2604 in our network
if ipv6 check fails some wget calls will fail or time out if wget defaults to trying ipv6 first. yum can have the same issue
if a domain on directadmin has a wildcard cert installed like a cloudflare cert that cert will be used for port 2222
you can test a php file like you are calling a website using strace: strace -y -tt -s1024 -u nurjahan -E HTTP_HOST=nurjahangroup.com -E REQUEST_URI=/ php index.php 2>&1| less
srs forwarding changes in cpanel v108. If forwarding is not working or return path is not set check the exim smart host config
you can reduce disk space quickly on cpanel using the admin scripts configs/clean_system.sh or on directadmin storage/clean_system.sh
cpanel webmail or phpmyadmin just spinning? cpanel internal phpfpm may be at max connections
run directadmin awstats for a user using /usr/local/directadmin/scripts/awstats_process.sh user domain.com
admin scripts have moved some directadmin commands to a cli. run /admin/storage/da to see all the commands
large systems that run as vms like webhosting systems can get slow on large backup restores due to removing useful disk cache. nocache command can resolve this.
80% usage on disk and ram should always be the max used. This gives room for spikes.
Getting geoip is not compiled in mod security on directadmin? Install the geoip dev/devel from apt or yum and rebuild modsecurity
To chown a symlink call chown with -h - -h, --no-dereference affect each symbolic link instead of any referenced file (useful only on systems that can change the ownership of a symlink)
If Account daemon is using 100% cpu you may need to rotate /var/log/wtmp - search wiki for Account-daemon
If pkg commands are slow on freebsd check if ipv6 is bound but not working - in that case it will wait to time out
A slow slog device in zfs will lead to high load - test with /admin/benchmark disk
xfs_quota on large file systems may time out. It is best over 1TB to run xfs_growfs after rebooting the system and it is online
if virt-rescue shows errors like error: udev not found  Things will probably not work or guestfsd: error while loading shared libraries: libsqlite3.so.0 and apt update may be running
cpanel webmail not logging in? Check cpanel php max children or restart cpanel css the calendar
If rewrite_confs hangs with a lock file a .bashrc under that user maybe causing the issue
