Discovery problem with an old Dell Powerconnect and Observium CE 23.9.13005

30 Nov 2023


      Hello,
After the last update i'm experiencing a bug on the discovery on an old 
switch.
This is a Dell PowerConnect 3448. :
Vendor/Hardware     Dell PowerConnect 3448
    Operating system     Dell PowerConnect (FastPath) 2.0.0.34
The bug appeared in this CE version, until now the info feedback was 
correct.
The SNMP poller seem ok.
Can you help me with this problem?
Here's the error dump :
#####  Module Start: sensors  #####
