** [tickets:#2777] dtm: Handle TCP connection failures gracefully**
**Status:** fixed
**Milestone:** 5.21.06
**Created:** Wed Jan 31, 2018 01:56 PM UTC by Anders Widell
**Last Updated:** Tue Mar 16, 2021 03:31 AM UTC
**Owner:** Thang Duc Nguyen
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
~~~
