Witam wszystkich!
Posiadam ogromny problem, ponieważ mam zainstalowanego apache na serwerze wirtualnym VPS (z obsługą panelu DirectAdmin), instalowałem wczoraj dodatek "ConfigServer Firewall&Security"
przed brute-force atakami i skonfigurowałem go poprawnie i działa, lecz w pewnym momencie apache zaczął pluć błędami, ogromnie one obciążają serwer (nie wspominając o pliku error.log który się zapycha i waży bardzo dużo), zwiększa się również wykorzystywanie pamięci RAM (dochodzi nawet do wykorzystywania w 100%) oraz powstaje dużo procesów pod komendą "top".
Po restartowaniu apache problem znika, lecz po minucie znów zaczyna się zapychać.
Proszę o szybką pomoc.
System zainstalowany to CentOS 6.
