v1.5.15rc1 Bug Reports and Comments

[summit-nathan]

We are also seeing the sfp ports drop every time any config change is applied. Also seeing slow increase in memory usage over time. We'll add some details once we have a bit more runtime.

[jpmoller]

Actually, you will note the far right ramp starts with higher memory available then the previous two ramps.....memory usage will grow with use, but new code should limit that...would be good to see it further on..

but in the meantime can you share below:

- switch model
- your switch configuration
- which oids you are querying on snmp
- share /var/log/messages and your snmp log.

Extra starting memory is cool, but I've already lost 12% of memory in the first 7 days of deployment. If the trend continues, the extra memory has gained us a few days, at most.

To answer your questions:

- switch model
WS-6-MINI

- your switch configuration

Hi Dave,

I've actually got some other OIDs we also scrape. Sorry for missing that the first time around

get:
- 1.3.6.1.2.1.1.3.0
walk:
- 1.3.6.1.2.1.2
- 1.3.6.1.2.1.31.1.1

[Dave]

no problem..info was very helpful, new RC coming soon

[jpmoller]

This seems like it might be the same issue?
https://forum.netonix.com/viewtopic.php?f=17&t=5384

I can see the same issue happening on our 1.5.14 hosts. I just checked a switch that had 6MB of memory left and the entire snmp.log file was 65MB of "No MemShared line in /proc/meminfo"

[Dave]

probably. This issue has been resolved, developer is testing before releasing...

[summit-nathan]

no problem..info was very helpful, new RC coming soon

Is the new RC expected to resolve the issues with the SFP ports losing link any time config changes are applied?

If not please let us know if you need additional info to track down this issue.

I don't think so. I disused this with the team and we want to investigate this first as I do not see this in my deployments.

After SNMP / memory leak is fixed we will lab it. At that time we may ask some questions and or request configs.
