IN some verions after update DA there are backup problems lookup changelog and forum for that
Also socket error i did see few time after some updates / changes DA or mariadb .
BUGS id don't know
Important what you did and changed exactly , i have to often problems doing more updates in one run with DA, better to do one at a time and test after it.
If you did DA and also Mariadb updates changes at same time ,
better to open ticket for that while if error wasn't there before!!!!!!
THE TEMP SOCKET ERROR SQL AFTER UPDATE IS happened more here on forum!
Here but not the only ones i think https://forum.directadmin.com/threa...gh-socket-tmp-mysql-sock-2.64117/#post-333434
So you did read that and should be time for SUPPORT TICKET AT DA or ask SMTALK!
I hope solutions and cause are posted in forum here?
