I know you don't want to hear about firmware, but the firmware upgrade specifically says that this warning message is resolved in 4.2.0.4 on up.  [URL] "Messages repeated in the switch logs <190> APR 28 19:39:22 10.1.208.10-1 STATSMGR[239558880]: collector.c(1066) 3445 %% Failure in function collectorGet. Resolution: SNMP walk/gets on counters for CPU/vlan routing ports not supported by platform no longer log a warning message. Affected platforms: All 4.2 supported platforms" Do you have any monitoring software on the network that could be polling the switch for these counters? Are you seeing any performance hits on the stack? Being just a warning, I don't think it will affect performance.  One solution would be to change the logging severity to not include warnings.  # logging buffered error the downside to this would be that you would not see any other warning messages. 
I have started getting STATSMGR errors filling the log files to the exclusion of any others on the core stack of PowerConnect 7048s. The current firmware is 4.1.0.6 and I am reluctant to upgrade the firmware after a firmware upgrade on a stack on N2048s corrupted their configuration. These run the network and any failure would be catastrophic. Any other suggestions for clearing than issue than upgrade the firmware? <190> JUL 21 06:22:02 172.16.2.20-1 STATSMGR[237994160]: collector.c(1066) 75143 %% Failure in function collectorGet Thanks!
