varnishncsa dies on HUP signal.

[Lars Jørgensen]

Same on RHEL 6, varnish compiled from source.

I've just filed bug #947 on it.

Subject: varnishncsa dies on HUP signal.

Hello.

I'm testing Varnish 3.0 on CentOS 5 (2.6.18-238.5.1.el5 x86_64) using
rpms from http://repo.varnish-cache.org/.

varnishncsa dies on logrotate, the logrotate script do a kill -HUP to
force refresh log files, this works fine on varnish 2.1.5 and previous
versions.

Debugging with strace:

root     24777  0.0  0.0  95272   356 ?        Ss   10:59   0:00
/usr/bin/varnishncsa -c -w /var/log/varnish/varnishncsa.log -D -P
/var/run/varnishncsa.pid

$> strace -p 24777

Process 24777 attached - interrupt to quit

write(2, "  errno = 4 (Interrupted system "..., 38) = 38

tgkill(24777, 24777, SIGABRT)           = 0

Thanks in advance.
Kind Regards.
