But excuse me? Something unexpected must be happening in your environment. udplogger will flush buffers upon '\n' or timeout (default is 10 seconds) or too long line (default is 65536 bytes). > > Also i fixed two segfault: > > 1) When send two messages in one second from different hosts or ports. > For reproduce just run > "echo test > /dev/udp/127.0.0.1/6666 && echo test > > /dev/udp/127.0.0.1/6666" > in console. I can't observe such problem. udplogger is ready to concurrently receive from multiple sources. 2018-01-06 23:30:08 127.0.0.1:33637 test 2018-01-06 23:30:08 127.0.0.1:47459 test 2018-01-06 23:32:52 127.0.0.1:36343 test 2018-01-06 23:32:52 127.0.0.1:49087 test 2018-01-06 23:32:53 127.0.0.1:43124 test 2018-01-06 23:32:53 127.0.0.1:40711 test 2018-01-06 23:32:53 127.0.0.1:48455 test 2018-01-06 23:32:53 127.0.0.1:60887 test 2018-01-06 23:32:53 127.0.0.1:49617 test 2018-01-06 23:32:53 127.0.0.1:56967 test 2018-01-06 23:32:54 127.0.0.1:44289 test 2018-01-06 23:32:54 127.0.0.1:52134 test 2018-01-06 23:32:54 127.0.0.1:57924 test 2018-01-06 23:32:54 127.0.0.1:54044 test 2018-01-06 23:32:54 127.0.0.1:42350 test 2018-01-06 23:32:54 127.0.0.1:56750 test 2018-01-06 23:32:54 127.0.0.1:33790 test 2018-01-06 23:32:54 127.0.0.1:55627 test 2018-01-06 23:32:55 127.0.0.1:46477 test 2018-01-06 23:32:55 127.0.0.1:34978 test 2018-01-06 23:32:55 127.0.0.1:41563 test 2018-01-06 23:32:55 127.0.0.1:34146 test > > 2) When exced limit of open files. > Just run "echo test > /dev/udp/127.0.0.1/6666" more than 1024 times. > I can't observe such problem. udplogger switches to a new file upon acrossing 00:00:00 of the local time. Simply repeating 1024 times can't reach max open files limit. Are you using special environment? What is the shell?
