Doing the full start of named. The I/O err in isc_lex_gettoken() appears only triggered when getc() hits EOF. ktrace is a little tough to get through with all the threads. But the thread that logs that error tracing back from that error being sent out a fd does stuff that looks like prepping for syslog like getpid, and then (priorly; working backward) read()'s the file apparently just peachy. RET read 228/0xe4 % wc empty.db 11 38 228 empty.db and the text reads just fine. So something is getting squirreled up above the syscall level. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
