I've taken steps to reduce the spikes in host counts, yet the segfaults after an IDLE_PURGE cycle are still prevalent. Anyone else having this issue? Any idea's how to fix this? I have gdb output and have posted it before. I can attach again if someone will actually do something with it. My skill set in C development/debugging is ever expanding, but they're exhausted for the time being.
TIA for any help!

Whomever decided to add this - good idea! ________________________________ From: Gary Gatten Sent: Friday, June 19, 2009 2:01 PM To: Gary Gatten; 'ntop@unipi.it' Subject: RE: [Ntop] crash after IDLE_PURGE I MAY have found the trigger for this. Our internal A/V / Spyware / whatever scans our entire internal network range causing nTop to "see" about 50,000 hosts. I'm not 100% sure on the correlation, but it appears Ntop Crashes every couple hours when this discovery process runs. Not *every* time - but often enough I'm convinced it play at least some role in these crashes. Any thoughts? My -x and -X values are high enough to not cause any issues... ________________________________ From: Gary Gatten Sent: Thursday, June 18, 2009 11:22 AM To: 'ntop@unipi.it' Subject: RE: [Ntop] crash after IDLE_PURGE FWIW this is the last entry in the log: IDLE_PURGE: Device 1 [NetFlow-device.2]: 719/8486 hosts deleted, elapsed time is 0.494425 seconds (0.000688 per host) ________________________________ From: ntop-boun...@unipi.it [mailto:ntop-boun...@unipi.it] On Behalf Of Gary Gatten Sent: Thursday, June 18, 2009 11:19 AM To: ntop@unipi.it; ntop-...@unipi.it Subject: [Ntop] crash after IDLE_PURGE On 3.3.10 rev 3780 - Solaris 10 x86. Had this same problem on 3.2 on FreeBSD... Anyway, nTop blows up after an IDLE_PURGE cycle. There was no entry in the log this time even though I have -t 5 specified. On FreeBSD it would through a signal 11. "One" of the reasons I updated Is to hopefully solve this problem. I'll run it in gdb again and post anything I find. Anyone else having this issue? I have a lot of hosts "monitored' - like... 12,000 ish at times. Not sure if that's part of the problem or why it's more apparent for me? TIA!
