Today I checked my error_log and found these errors in it.

I have increased the php memory limit via cpanel php settings. But my site is not a very active one. It is only receiving 2000 pageviews daily. I am on shared hosting with 1GB of physical RAM and 4GB of virtual RAM.
Sometimes my site gives 508 resource limit reached error.
I have tried change the host but still same problem.
