recntly i have noted that my ram usage is going very high and sometimes it hits 100% which end up with server unreachable error for visitors.
i am not sure how i can solve this. even i tried following options
disabled all plugins - no effect
changed theme - no effect
change theme and disable all plugins at one - no change
re-installed wordpress using dashboard inbuilt option - no effect
i have only 400 visitors per day but my Akismet catchs over 1000 spam comments daily.
if anyone could help me i am very thankful
