LOG: unexpected EOF on client connection

Hi list,

I am doing a benchmark in my database but it is spent too much time.

I was looking for my log file but I could not understad clearly what it says.

The log is like this:

INT: Consider increasing the configuration parameter "checkpoint_segments".
LOG: checkpoints are occurring too frequently (4 seconds apart)
HINT: Consider increasing the configuration parameter "checkpoint_segments".
LOG: checkpoints are occurring too frequently (5 seconds apart)
HINT: Consider increasing the configuration parameter "checkpoint_segments".
LOG: checkpoints are occurring too frequently (5 seconds apart)
HINT: Consider increasing the configuration parameter "checkpoint_segments".
LOG: checkpoints are occurring too frequently (8 seconds apart)
HINT: Consider increasing the configuration parameter "checkpoint_segments".
