Process panic

[Rentian Huang]

Greetings Cloverleafers!

We currently have an Ib thread which handles everything, i.e., ADT, ORD, RES, CHG, from our front end ADT system, and it panics sometimes..

Can anyone give us a best pratice? Normally, do you separate Ib ADT, ORD and CHG into diff thread? Do you have the same panic problems???

Thanks in Advance!

Rentian,

Can you post a copy of your logfile with the eoconfig set to enable_all?  Panics can be caused by numerous different conditions.  Usually I start by turning up the eoconfig and trying to re-create the problem.  If you can re-create the problem, let us know exactly what you are doing.  One thing to look at…. how many threads do you have assigned to the process and site?  Has this interface been up long and when did the panics start?  Additional info would be great.

Most of our ib thread requirements are driven by the manner in which the source system supplies the messages.  Usually we have a separate thread for ADT, Orders.  Not sure if this applies but we stay away from using the multi-server option for our tcp/ip inbound connections.

It would also be helpful to know what version of Cloverleaf/Rev and your OS.

David and Rick,

Very sorry for the confusion, we are running Platform V 5.2 on AIX. And you are absolutely right, recreating the problem is the best way to identify the cause, but we have accidently removed the log file, I will attached the log file next time with enable_all eoconfig.

For the process that paniced, there’s only 1 thread, but we have 17 thread and 7 processes on production. The interface has been up for more than 5 year and the panics started recently, almost all of them happened after we upgraded to Platform V 5.2. We know it’s NOT a good pratice to put everything on one Ib thread but that was what it was setup before we came here.

We don’t use multi-server here…

Can you help us more? Thanks!

Sam 🙂

Rentian,

There is a specific parameter that you need to have set in the AIX world with Platform V; I believe the parameter is the AIXTHREAD_MNRATIO =1:1 (or something like that);  check with Quovadx support to get the specifics.  If this parameter is not set, you can experience sporadic panics.  This parameter is set in the /etc/environment file.

Hope this helps.

Is there any particular place in the /etc/environment file that this parameter needs to go in?  We are having the same problems, and seems like now once a week we are experiencing a process panic (same process).  Should I have bounced all of my processes/rebooted the server after the change was made?

Any help is appreciated.

April,

Check with Quovadx support, they should be able to provide you with the information.  I believe there is a section in the /etc/environments that was added by the Cloverleaf install and you can add it under there.  I also think you have to stop and re-start anything running by the ‘hci’ user to invoke the change.

Set the AIXTHREAD_MNRATIO environment variable for AIX5.x  to 1:1.
