[srslte-users] Crash in srsEPC

[Pedro Alvarez]

What steps are you taking for this to occur? Can you replicate this easily?
Which distribution are you using? Are you using a COTS UE or srsUE?
Are you using srsENB or something else?

Can you send the backtrace, the epc.log, enb.pcap and the epc.pcap?
