idle in transaction...unexpected EOF on client connection

Hi Everybody,

I see in serverlog many entries that read:
 <gadb 2007-11-09 13:13:47 PST idle in transaction>LOG:  unexpected EOF on client connection
 <gadb 2007-11-09 13:23:08 PST idle in transaction>LOG:  unexpected EOF on client connection
 <gadb 2007-11-09 13:23:44 PST idle in transaction>LOG:  unexpected EOF on client connection
 <gadb 2007-11-09 13:25:42 PST idle in transaction>LOG:  unexpected EOF on client connection

This occurs regularly and frequently and I am
wondering if it is indicative of any underlying
issue(s).  Would you please let me know what
you know?

Thank you.
