Hi, I am using a Sun SPARC 20 with Solaris 2.5.1 and OS recommended patches loaded. I had managed to compile nntpcache 1.0.6.5 with gcc 2.7.2. The binaries is running fine except if I give any option/arguments I get a core dump. Any ideas? On the other hand, does anybody know where can I find some info on the tunings? Thanks.
