Hi,

We are facing issue with the RES memory. Below is the o/p of
top command. It shows that writer process reserved 3.8g. We have observed that
if it increased to 3.9g we need to restart the db. Otherwise it hangs.  Kindly 
suggest us the good way to figure it out this issue.   shared_buffer
is 3 GB.
