RMI TCP Connection

On two computers i have the same Java apllication. Every of these two apllications has its own database (Oracle 8). Few days ago I had a problem with starting one aplication. From then in log file of the aplication with a problem there is a message:

INFO cleanup connection: RMI TCP Connection(70) -xxxx.xxx.xxx.xxxx used: 320 min :10 avr: 21 max: 27

INFO connection state:

INFORMI TCP Connection (74) -xxxx.xxxx.xxxx.xxxx used: 17 min: 18 avr: 20 max: 22

xxxx.xxxx.xxxx.xxxx is network address of distance server where from I can connect at the PC.

OS is Linux

What this message means?

Does problem connected with database?

How to fix it?

Any information is good!
