Hi Sudhakar,

I have raised CR 01614853 for the UMU not initialization issue and when that issueis fixed then we shouldnt run into cnode internal snyc error message. For nowthere is no workaround except RNC MIB rebuild. But in case we see the notInit(there should be a VM degraded alarm @WMS for it), we can reset just one VM andavoid the rebuild.

What is the severity of this CR? If we got in the problem and only solution is RNCrebuild then impact is huge!Please ensue we receive wa and/or final solution asap

Hi Rameez,

Site team has below concern, kindly help on it:

What is the severity of this CR? And If we got in the problem and only solution is RNC rebuild then impact is huge!Can we have other WA and/or final solution asap.

Thanks,Mohmadi.


The severity of this CR is critical. The designers are working on it right now.To avoid the RNC MIB rebuild, we can also check which UMU's are not initializedand only reboot those VM's.Final AP will be provided to the customer later today.

Best Regards,Rameez

Hi Mohmadi,

We should have seen alarms on the WMS complaining about the UMUs are degraded butwe dont see any. Thats why the local team didnt know/notice about the UMUpostmortems before running the WO. The UMU postmortems are very critical and a CRshould be raised as soon as we see it. For now we can apply the AP and once wehave a permanent fix then we shouldnt see the UMU not initialized issue anymore.

The UMU not init is happening randomly on different UMUs and the OMU is not awareof it. Thats why the OMU is not sending an alarm to the WMS complaining that someof the UMUs are degraded and not initialized. This is an issue that needs to befixed as well.

Thanks,Rameez

Hi Mohmadi,

Here is the reason why the UMUs were in bad state and not initialized.

UMU Reset happened due to Integer Divided by zero Exception. At the crash point weobserved a zero value for a data member numOfTb (Number of Transport blocks inthe frame) which is not expected in this flow.Uplane is trying to process the filler/silent frame to power control mechanism,where the data member numOfTb coming as zero is used for calculation, which iscausing the UMU Reset.

We have the fix available for it. It is being tested in our lab first and whenits confirmed that the issue is fixed. Then we will provide it to the customer.

Best Regards,Rameez

UMU Reset happened due to Integer Divided by zero Exception.

For this fix is available and testing is ongoing in the TEC lab, will keep youupdated on the progress of it.
