Our system is not responding. I cam in this morning to fins a message. kprint: 18 messages suppressed dsk cache overflow disk space is fine btw. lots of it available. i then rebooted...everything is fine for few mins and then bam it all stops.....terminals stop responding. i then get soemthing like.. dpti1: trying to abort cmd 435345 dpti1: bus reset or something like that. that, i think has to do with our adaptech i02 raid controllers. then after i see those messages i start getting iptable drop messages. a weird one... i get a message telling me that a packets or packets were dropped because of nul-ip-spoof src=0.0.0.0 dst=255.255.255.255 spt=67 dpt=68 could all this be irq conflicts? I say this because of the src=0.0.0.0 and my raid controller seems to be giving errors..... the adaptech after-post utility says everything if fine.....raidutils says everything is fine could i have been hacked?? i see a lot of hijack attemts thru ssh over the weekend...... could not read the whole log..system froze by then.... any other thing?? please help....
