After moving to a new server, and a little bit of a battle to get snips
working on the new 64bit platform, all the monitors seem to work, except
hostmon is falling over after a few successful polls, eventaully it dies.
strace output looks like:
lseek(4, -400, SEEK_CUR) = 8000
write(4, "hostmon\0\0\0\0\0\0\0\0\0localhost\0\0\0\0\0\0\0"..., 400) = 400

Anyone seen similar before?
We have modified some things slightly to get it to compile on the new server
(Linux 2.6.14 kernel, x86_64 AMD Opteron(tm) Processor 246)
If anybody wants to see the code, then I can make it available.
Everything else seems to run okay, except it didn't like some of the rrd
files from the old system, so I just deleted them.
snipstv and eventselect compile and run, but crash with this segmentation fault:
open("/etc/localtime", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0644, st_size=1323, ...}) = 0
fstat(4, {st_mode=S_IFREG|0644, st_size=1323, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x31babfa16000
read(4, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\7\0\0\0\7\0"..., 4096) = 1323
close(4) = 0
munmap(0x31babfa16000, 4096) = 0

I know long term we would be better moving off snips as although it's pretty
much developed and does what I need, it is a dead product.
Last time I looked at this, there wasn't really much out there that has
similar functionality and is as lightweight and simple. (i.e, I suppose we
could use nagios but that's overkill for what I want, and it seemed messy
getting it to work across multiple boxes, but things may have improved with
it since then.)
Is anybody still using snips? Am I the only one? :)
