This problem exist for me on all glibc incarnations as far as I'm aware. It also exists in Perl5 / Syslog:pm - but I wrote a local patch for myself for that. Admittedly, I probably could write a patch to glibc, but then I'd have to get it into the real glibc source so that it doesn't get overwritten by every new glibc RPM release. I just thought it would be easier all round to provide for as near 'non-stop' functionality across syslog-ng/SIGHUP as possible.

I previously enquired whether it would be possible to allow for a keep-alive option on Unix DGRAM sockets to help avoid the situation on some platforms when

daemons

such as sendmail have the /dev/log socket 'whipped from under them' during syslog-ng/SIGHUP.

Why not fix the libc code on those platforms so it does basic sanity checking on the socket, and re-opens the socket when it discovers that its cached filehandle for /dev/log is invalid? I encountered this on NetBSD and it was an easy library fix (it's patched in all current releases (1.5.3 and 1.6 candidates) - what OS are you using? _______________________________________________ syslog-ng maillist - syslog-ng@lists.balabit.hu https://lists.balabit.hu/mailman/listinfo/syslog-ng Frequently asked questions at http://www.campin.net/syslog-ng/faq.html *************************************************************************************************** This E-mail message, including any attachments, is intended only for the person or entity to which it is addressed, and may contain confidential information.
