Which version is this? I think this issue has been solved a while ago.

Please send complete eNB and EPC logs in info level. In general, however, it might be worth to try another EPC, like open5gs. The srsEPC is a light-weight testing EPC and was never intended for serious use.

Do you mind trying my branch #647?

@mazimkhan As @matan1008 said we would be really grateful if you could test his branch with your exact scenario. If you can, could you also post the log entries (like above) when the rollover happens?
