Pozdrav,

S vremena na vreme VPS server koji koristimo postane nedostupan, svi servisi su nedostupni i jedina pomoc je restart od strane hostinga. U pocetku smo se nagadjali mi i oni do koga je, receno nam je da MySQL baza koju koristimo nije optimizovana (sto je istina, jer nikada optimizaciju nismo radili niti znam to da uradim). U svakom slucaju prebacili su nas tada na drugi server i radilo je ok.

Od pre nekoliko nedelja isti simptomi, a pocelo je sve sa neuspesnim automatskim update-om cPanela, sto se moze videti i u poruci koja mi stize na mejl svake nedelje:

/usr/local/cpanel/scripts/upcp was running as pid '13263' for longer than 6 hours. cPanel will kill this process and run a new upcp in its place.

/usr/local/cpanel/scripts/upcp was running as pid '14623' for longer than 6 hours. cPanel will kill this process and run a new upcp in its place.

Takodje tu je i izvestaj o hang procesu (jedan od mnogih):
The chkservd sub-process with pid 17768 ran for 15218 seconds. This sub-process was terminated when it exceeded the time allowed between checks, which is 300 seconds. To determine why, you can check /var/log/chkservd.log and /usr/local/cpanel/logs/tailwatchd_log.

Da li neko moze iz gornjih podataka da mi razjasni eventualne uzrocnike problema, kako bih znao sta dalje ciniti. Proverio sam i log fajlove ali meni to nije razumljivo. Da napomenem da na shared hostingu koji smo koristili (druga firma) nije bilo ovakvih problema niti ovako ucestalih, a preselili smo se zbog prostora koji nam je trebao.
