I found that if you append a & to the args in the system call, mythlogserver launches properly when mythfrontend is started, logs appear where they should, and mythfrontend exits immediately without hanging. This is in combination with the no daemon patch. </font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><font face="Verdana, Arial, Helvetica" size="2">I also found that when mythlogserver is launched on demand by launchd, as mentioned previously, logs aren't being written and mythlogserver quits after 5 minutes even if the frontend is still running. However, if you quit mythfrontend and restart it while mythlogserver is still running, logs will work normally at that point. What I also did was to disable the launching of mythlogserver from mythfrontend (since launchd takes care of it) in order to prevent the two mythlogserver processes (one of which quits automatically). So is this an issue with zeromq, a race condition perhaps?</font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><font face="Verdana, Arial, Helvetica" size="2">Yves</font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><br></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div><div><font face="Verdana, Arial, Helvetica" size="2"><br></font></div></body></html>
