Gurcharan, I believe this particular issue of VenueClients disconnecting (or being disconnected) can be fixed by upgrading to accessgrid3.2. Our UQVislab node which is up 24/7 has never had this problem since running the 3.2 version. On the other hand, 2 other machines in a special test environment and still running 3.1 are regularly disconnected. I've just now updated one of them to 3.2 to try to confirm that the issue is fixed after upgrading; I'm pretty confident though. chris > anything we can do to address and fix this would surely help AG > survive and thrive. > > -gurcharan > > Jason Bell wrote: >> G'day Jeremy >> >> I honestly cannot explain why I need to do "regular" restarts, I just >> find that if I do, the bridge is more stable and more reliable. >> >> For us, it is better that every time a person wants to connect to the >> bridge, that the bridge is up and running. >> >> Sorry I cannot be anymore helpful! >> >> Thanks, >> Jason. >> >> -----Original Message----- >> From: Jeremy Mann [mailto:[email protected]] Sent: Monday, 3 >> November 2008 09:48 AM >> To: Jason Bell >> Cc: [email protected] >> Subject: Re: [AG-TECH] AG bridge woes >> >> On Sun, Nov 2, 2008 at 6:06 PM, Jason Bell <[email protected]> wrote: >> >>> G'day Jeremy >>> >>> For my personal AG bridge, I have a "cron" job that restarts the >>> >> bridge >> >>> every night. >>> >>> I am also in the process of assisting to setup a number of bridges >>> around Australia and I am experimenting restarting the bridges just >>> >> once >> >>> a week. >>> >> >> Thanks Jason, but is that really acceptable?
