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

ysgaga commented 2 years ago

Hi,andrepuschmann, My version is 21_10,it is newest.

andrepuschmann commented 2 years 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.

For me this happens when UE IPs are exhausted image

matan1008 commented 2 years ago

Do you mind trying my branch https://github.com/srsran/srsRAN/pull/647?

andrepuschmann commented 2 years ago

@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?
