-- correction --I was wrong.. there was nothing wrong with NAM last night... We had an extremely high volume attempt to breach our systems... for example, the box on which the problems occurred, in the last hour we had:
root@5mod:/var/log# grep -c ail auth.log 122358or 122K attempts to hack the box... what happened overnight is logs filled up the system not allowing nam to write to disk...
The source appears to be somewhere in China... they could have chosen me because that rack of servers sits directly on a 10GB Hurricane Electric backbone, or it could have just been a random event... In case they were targeting weather related systems, everyone may wish to look deeply into their logs to see if anyone dropped an egg on your system.
Sorry to bother! cheers, --patrick …………………………………………………………........... Patrick L.

Rather serious errors transpired with NOAAPort NAM over the evening, and continues into this morning... this graphic contains 2 columns of nam directory listings... note that bot 12z and 06z runs contain errors.. what is interesting is that some hours report as 0 bytes (yet they still report), however other hours contain... well, several hour's worth of runs?http://modelweather.com/files/noaaport/2016.12.15.noaaport.nam.pngthis box has redundant independent direct noaaport feeds (2 dishes, 2 novras, both feeding etc..)worried! .... :) --patrick …………………………………………………………...........
