JVM continually fails
Hello,
I have C8.2.0.4 set up as a test environment with 3 W2K8R2 64-bit "clustered" (via software), and a dedicated W2K8R2 w/ SQL Server 2005 SP4 for DB.
Intermittently (or on a certain interval that I have not figured out yet), the system goes down with the "not ready" message.
When I check the ConnectProService log, it shows:
2012/02/12 17:38:49 | STATUS | wrapper | Launching a JVM...
2012/02/12 17:42:06 | STATUS | wrapper | on_exit trigger matched. Restarting the JVM. (Exit code: 1)
2012/02/12 17:42:10 | STATUS | wrapper | Reloading Wrapper configuration...
2012/02/12 17:42:11 | STATUS | wrapper | Launching a JVM...
2012/02/12 17:47:24 | STATUS | wrapper | on_exit trigger matched. Restarting the JVM. (Exit code: 1)
2012/02/12 17:47:24 | FATAL | wrapper | There were 2 failed launches in a row, each lasting less than 300 seconds. Giving up.
2012/02/12 17:47:24 | FATAL | wrapper | There may be a configuration problem: please check the logs.
2012/02/12 17:47:24 | STATUS | wrapper | <-- Wrapper Stopped
I set up Adobe Connect Service, FMS, and FMG to restart on failures.
Is there an update for JVM that I am missing? Why does JVM keep failing?
TIA
Kevin

Re: JVM continually fails
Welps, I'll answer my own question :)
I believe the reason why my servers continually failed was because of a time discrepancy. There is currently a problem with my cloud vendor where the clock has been stopping (bug), and when the time discrepancy gets large enough between server and DB [~5 minutes or so], the Connect service will crash.
Who would've thunk it?

Re: JVM continually fails
I think i have a similar problem to you but would like to know how you verified it was the time discrepancy between the connect server and the db?
I "think" my issue is related to how I backup the virtual servers which run connect and db server using snapshots and what happens when the backup process removes the snapshot at the end of the backup process
Edit:
I have my connect and db servers setup to sync with external sources via http://technet.microsoft.com/en-us/libr … S.10).aspx but it appears that the windows time service while set to automatic is only automatic when a member of a domain http://www.mcbsys.com/techblog/2010/09/ … matically/ because the service wasn't started when I checked on connect server
I'm going to leave that change sit a while to see if it makes a difference but my next change would be to look to the vmx file or pre/post snapshot actions to see if there is anyway better handle time slips

Re: JVM continually fails
I don't know if manually setting the times astray from each other (db and app servers) would reproduce the problem. I can try it, but the problem was with my cloud vendor and a time drift bug that has now been resolved. (bug with hypervisor) The service no longer crashes.
