Groupwise 2012 stops sending transferring to Gwava 3rd Send

I had issues with Groupwise 2012 orginally that the gwia would come up "dead", so what I did was setup a cron job to down groupwise and start it up at 6:30 am and at 6:45 to do the same with Gwava 6. The email works fine for a couple days, then it stops transferring the emails from the gwia/send directory to the gwia/3rd/send. I have to restart the gwia so it will start sending again. This really has been annoying and I have had to be checking up on the gwia every day... The groupwise 2012 is on a SLES 11 SP1 GM and installed on a new server..
