llme,
no, it’s not related.
In your shoes, i would just do a gpeh trace, extract a failure after adm, and see the cause 🙂 That takes one hour and then you’re done !
In your previous pmx extract, it’s a pity you didn’t put the number of fail after adm. In a previous post though, you stated it is equal to the number of rrc failures.
And i told you the main causes for fail after adm : it is a RNC or transport network or Core Network issue.
Have you chercked your RNC load ? Maybe the RNC is in overload ?
GPEH would tell you all that. If you have no decoder for gpeh trace, i can help (but take a very small trace : 30mn in one worst site + CM export).
Cheers
