The ports and source version of Boa is identical, and the only patches appear to be some minor path changes, and the following in Makefile: -LDFLAGS = @LIBS@ -g -CFLAGS = -O -Wall -g +LDFLAGS = @LIBS@ +CFLAGS = @CFLAGS@ It doesn't compile 100% cleanly out of the box: y.tab.c: In function `yyparse': y.tab.c:314: warning: implicit declaration of function `yylex' boa_lexer.l: In function `yylex': boa_lexer.l:82: warning: implicit declaration of function `yyerror' boa_lexer.l: At top level: lex.yy.c:1175: warning: `yyunput' defined but not used get.c: In function `get_cachedir_file': get.c:335: warning: long int format, int arg (arg 5) request.c: In function `get_request': request.c:79: warning: large integer implicitly truncated to unsigned type util.c: In function `get_commonlog_time': util.c:141: warning: assignment makes integer from pointer without a cast request.o: In function `process_header_end': /usr/src/boa-0.94.8.3/src/request.c(.text+0x9fc): warning: tmpnam() possibly used unsafely; consider using mkstemp() index_dir.c: In function `index_directory': index_dir.c:141: warning: passing arg 3 of `scandir' from incompatible pointer type > > This is the same machine that was crashing a while back, it's now running > > on all DIMM instead of SIMM+DIMM and it's been running well, just rarely > > above 0% idle.

The site is sending out approximately 12-14Gb of data daily, the bulk of that being 10-20k images. The underclocking was an attempt to fix the crashing problems, which have not reoccurred since I removed all SIMM memory; I haven't yet changed the clock speed back. The machine is not just serving static content, it's also generating HTML on the fly (via PHP) and running 111 background processes to fetch webcam images and process them, so the load can momentarily spike or dip even when there is a relatively constant stream of HTTP fetching. last pid: 36124; load averages: 16.60, 27.51, 30.73 up 0+19:02:47 17:51:51 280 processes: 22 running, 257 sleeping, 1 zombie CPU states: 36.2% user, 0.0% nice, 47.0% system, 16.4% interrupt, 0.4% idle Mem: 75M Active, 9052K Inact, 29M Wired, 5508K Cache, 22M Buf, 4528K Free Swap: 256M Total, 5176K Used, 251M Free, 1% Inuse Note the idle state and the small amount of swap used. The number of processes may also be an issue. Any pointers on where to start with tweaking? Thanks for your help... The site is http://www.camrecord.com/ if you want to see an example of images being missed. ;\ Cheers. -- Rowan Crowe http://www.rowan.sensation.net.au/ Sensation Internet Services http://info.sensation.net.au/ Melbourne, Australia Phone: +61-3-9388-9260 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
