I have searched an archive of this mailing list, but have not found
anything; so please be easy on me if this has been asked before ...
I'm in the process of configuring diald for RH5.0, kernel 2.0.33.
Fairly regularly, I'm encountering a situation where any further
attempt to make diald dial up, start diald or initiate a
ppp connection by hand simply block and never return. Additionally,
any other process accessing the syslog facility (like su, login,
init, etc.) seems to do the same, resulting more or less in a
paralysis of the whole system.
Browsing the list today, I stumbled upon hints that the RedHat rpm
of diald-0.16.4 which I installed adds a line to syslog.conf, to
the effect that syslog is writing to the diald fifo. This write can
block, effectively hanging syslog. (Did I get it right up to here?)
One person on the list suggested a /etc/rc.d/init/syslog restart
to reanimate the system, which I can not try at the moment, because
I'm at work. Another person suggested that the whole concept of
making syslog write to a blocking fifo was a Bad Idea (tm), and
the offending line in syslog.conf should be trashed altogether, but
warned that modifications in other places would be necessary, or
otherwise diald would break.
My questions are:
o Is the blockage really caused by syslog writing to the fifo?
o What are the necessary modifications to keep diald working after
one removes the offending line in syslog.conf?
o Are there any other ways to avoid the problem?
Thanks in advance,
-Chris
