TTCN-3 L1CTL-related test issue

Hi. While experimenting with BTS TTCN-3 tests I've got some of the tests misteriously failing with: FBSB Failed with non-zero return code 255 Anyone hit this before? Any ideas what could be causing this? -- - Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Harald Welte
