syslogd and pipe

[luongo]

Hello,

I have syslogd writing to a named pipe, which is read by another client program. At the same time, I also have logrotate running to keep the log file small. As part of the post action of logrotate, I send HUP signal to syslogd. The reason I do this is I think since the old file is now with new name and a new log file is created with same name, I want to force syslogd to open the log file again so that it does not write to the old log file which has a different name now. However, the problem I have is that after the syslogd is restarted, the named pipe seems to be clogged, the client doesnt seem to receive any message from the pipe. But if I manually does a cat <named-pipe>, I can see the messages. Is there anything I miss when restarting syslogd? Do I need to make the client program that reads the pipe also reopen those pipes?

Thanks in advance for your help.

-LG

I suspect that you need to hup the app that is reading from the named pipe.
