cannot run ttcn3-msc-tests locally, any ideas?
by Neels Hofmeyr 04 Feb '23

04 Feb '23

I'm currently stumped here, thanks for any hints what to try next: All of a sudden, all attempst to run the MSC_Tests.ttcn locally, from osmo-ttcn3-hacks/msc, are failing with the same error. This happens regardless of the selection of tests to run, i.e. even if not related to SMPP at all. Our jenkins doesn't seem to encounter that error. It seems that titan is sending an invalid SMPP packet, then something happens that SMPP_Emulation does not expect to happen, and the entire run of tests is aborted. I've already tried to 'make clean' in the osmo-ttcn3-hacks root dir, 'make deps', and re-ran the gen_links and regen_makefile scripts in msc/. I'm still getting the same error: none -> fail reason: "Unexpected SMPP from peer" [...] terminate called after throwing an instance of 'TC_Error' ./MSC_Tests: Abort was called /usr/lib/titan/libttcn3-parallel-dynamic.so(_Z14signal_handleri+0xa3)[0x7f1e319950a3] /lib/x86_64-linux-gnu/libc.so.6(+0x3bf90)[0x7f1e3085af90] [...] /usr/lib/titan/libttcn3-parallel-dynamic.so(+0x24c077)[0x7f1e3164c077] Error: Receiving of data failed from the MTC at 127.0.0.1 [127.0.0.1]: Connection reset by peer MC@x43: The control connection to MTC is lost.
