Agent Stopped

I submit a ticket for this before but didn't have the information i'm providing here. basically, the execution agent stops once in a while for no apparent reason. When it stopped last night, I went into the event log and found couple of errors. I have attached a screen shots for your review. This is not a major issue, but I'm wondering if you have any ideas to prevent it. Thank you

Looks like it is postgre problem
