I have no time for now to investigate deeper. I rebuilt server using nginx even if performances are bit slower. but at least, no more dead lock.
my 2 cents feeling is that OLS is killing "long" queries, which are remaining stuck between php and mysql, which is ending in dead lock. but as no...
same issue here. wordpress installed on a fresh dedicated server, and lot of "possible dead lock". error log is not helping, no error on wordpress side, nothig. cpu usage is very low.
Completly unable to find root cause of those dead lock which are hanging the page response.
Hello
I'm with debian 10, but it's impossible to compile php :
checking for sqlite3 > 3.7.4... no
configure: error: Package requirements (sqlite3 > 3.7.4) were not met:
No package 'sqlite3' found
checking on server :
# sqlite3 --version
