I am seeing a recurring event happen with Discovery. Things will be going along great then all of a sudden I will get a handful of servers failing DNS Scan and Quick Scan. Checking the system I see 7-10 task manager entries flashing SNMPGET.EXE entries every few seconds. I've tried killing the tasks but they keep showing back up. The only cure I can find is to reboot the server. This is OK for a one-off issue but not 7-8 servers at a time. Has anyone else seen this and know of a way to correct it?
Interesting, I see that you did create a ticket similar to this issue previously.
However, it looks like the root cause was never found and was not identical to what you are reporting here.
I would recommend creating a follow-up ticket to further investigate this in detail.
This appears to be very sporadic and inconsistent behavior from your reports.
May I ask if you are using Classic Monitor > SNMP or is there a specific reason you have SNMP Enabled on the Discovery scan?
let me know your findings as I'm also having some issues with the discovery module which haven't been solved for the moment.
I am using the discovery scan as a way to check hourly (as that is the smallest increment possible) for any other network devices added that we may not be aware of. If there is a better way to do that, then please let me know.
Regarding the prior ticket, after further troubleshooting, I found multiple instances of nmap running (stuck actually) that resolved the issue once killed and with out a server restart. For this current batch of issues, nmap is not what I am seeing, snmpget.exe is what shows now.
