[Ahmed Al Katranji]

Hi All,

Sorry for the multiple emails, I have modified the code to print out the
error, and here is what i got:
Built in Release mode using commit d045213f on branch master.


---  Software Radio Systems EPC  ---

Reading configuration file /home/zynqmp/.config/srslte/epc.conf...
HSS Initialized.
Subscribing to sctp_data_io_events failed
sctp_data_io_events - SCTP error code is 22, error string is Invalid
argument
MME S11 Initialized
MME GTP-C Initialized
MME Initialized. MCC: 0xf001, MNC: 0xff01
SPGW GTP-U Initialized.
SPGW S11 Initialized.
SP-GW Initialized.
*** buffer overflow detected ***:
/home/zynqmp/srsLTE/build/srsepc/src/srsepc terminated
srsLTE crashed... backtrace saved in './srsLTE.backtrace.crash'...
---  exiting  ---


Can you help?

Thank you,
