Hello, About bugs of varnishncsa in tickets #633<http://varnish-cache.org/ticket/633>and #685 <http://varnish-cache.org/ticket/685> I have modified varnishncsa.c,
It ignores duplicated ReqEnd and dump bogus in stderr ¿may be changed to system error log??? 1. Get XID from ReqEnd 2. If XID == 0 then ignore ReqEnd 3. If XID != = but bogus == 1 then print bogus request in standard error. It works me ok in Solaris 10, and avoid coredumps.
