When TCP connect() fails, DTM tries to add a -1 file descriptor to epoll(), which fails and results in the DTM process exiting.:

rootfs/var/PL-3/log/messages:Jan 31 14:18:40 PL-3 local0.err osafdtmd[425]: ER DTM :Connect failed (connect()) err :Connection refused
rootfs/var/PL-3/log/messages:Jan 31 14:18:40 PL-3 local0.err osafdtmd[425]: ER DTM: epoll_ctl(7, EPOLL_CTL_ADD, -1) failed: 9
