[srslte-users] ENB Error during srsLTE network running

[Tomasz Anuszczyk]

Hello.

I am testing a combination of srsLTE network. My computer system is Ubuntu
18.04.5 LTS. Installed release version of srsLTE is 20.10.1. Installed
version of UHD is 4.0.0.0.

1 test:
srsLTE network operated correctly for four whole days, or 96 hours.

2 test:
srsLTE network worked for 8.5 hours, then the terminal with srsenb turned
on displayed the following message: "terminate called after throwing an
instance of 'std::length_error' what(): basic_string::_M_create".
Please look at log from srsLTE.backtrace.crash at the very bottom.

3 test:
The same situation repeated as in test number two:  "terminate called after
throwing an instance of 'std::length_error' what():
basic_string::_M_create".

With each subsequent test, the connection remains for a different amount of
time, but the same error occurs on ENB terminal -  'std::length_error'
what(): basic_string::_M_create. During the tests, the internet was working
properly. What is the cause of the error? Please help.

Best regards Tomek.
