Furthermore, building the binary with debug mode (WITH_DEBUG=3Dyes) stopped the bug from being triggered and we cannot get a coredump to investigate. We then forced the debug build with optimisations on (-O2) and we still can= not reproduce the error. We have seen this happening in fd 1 and fd 2. The command `fstat -p pid` returned root rsyslogd 1073 2 - - bad that means bad file descriptor in stat(2) and errno.h (EBADF). --=20 You are receiving this mail because: You are the assignee for the bug.=
