spring mvc - Hibernate session closed after time -

i'm trying test application on home webserver running ubuntu, has come attending if allow session open , come time later , seek login throws error:

reason: not open hibernate session transaction; nested exception org.hibernate.transactionexception: jdbc begin transaction failed:

and if seek login 1 time again throws error:

reason: not roll hibernate transaction; nested exception org.hibernate.transactionexception: rollback failed

i don't have else work with, because logs not working tough did on windows.

also im not totally sure reason letting session on, or because of long time of inactivity. know there's little info work with, hope can give advice. in advance.
