Hi i have an ePMP as AP , i was able to upgrade al SM connected to that AP to 2.4.2 (from 2.4.1)
but when i tried to upgrade the AP module an error is shown in web page notification icon:
Error. Unpack failed - damaged or wrong package format.
Looking forward seems to be a problem with memory logs sent to syslog servers and shows this:

I use cacti to monitor that AP, and it seems that snmp is doing bad stuff inside
I thougt that one reboot whould do the memory freeing possible but, it's completely necessary? i mean, can i do something so when upgrading reboot once?
