I think just creating/destroying PPPoE sessions will not make the issues happen. Another think i forgot to tell, i disabled syslog in mpd5 Makefile: # Set syslog logging facility. Change LOG_DAEMON to whatever you like. # Comment this line disable syslog (3) support #SYSLOG_FACILITY=3D LOG_DAEMON But even with syslog disabled i ran into with uwrlck issue. Then my last try was to set cpu affinity as i told before. I read the link you sent. Looks like an issue with vsyslog(). So my questio= ns is: even with syslog facility disabled on mpd should i expected this kind of behaviour (stuck)?=20 Thanks. --=20 You are receiving this mail because: You are on the CC list for the bug.=
