I don't want to blame a mod...again... so I'll say this very carefully.....
When disabling the httpBL mod the VPS didn't stress at all.... so this mod could be the reason but I don't know for sure. With this mod enabled the VPS went very oft into STALE or WARN status but the status is (since yesterday 7 march19:02): OK.......
Maybe the mod 'eats' to many memory from our VPS (2Gb RAM)? I run only 4 websites: 1 big and 2 small websites and a X-Cart webstore
We'll see what is going to happen the upcoming days..... we also upgraded the VPS with 512MB RAM this morning
SPAM/bot protection is now (only): Stop Spammer, Login Detector and Disable Tor access to forum
I hope this is enough for now.
