I haven't worked with ESS logs. Can WireShark parse them? This is all for log id 153237764, in case you want to dig into the problem (which is wider than just my device). The encrypted file was uploaded to the site too.
Ah, didn't realize there was xerox code in those files too. Interesting.
Network traces is difficult with the location of the device (prohibits hub+pc+wireshark capture) and networking won't enable a trace at the switch/router level.
Abbreviated issue is that randomly the printer's SNMP agent crashes. It doesn't happen on demand. Some times it takes days or hours to occur. When this occurs, the following is displayed on the web interface:
16-586 The Network Management function has failed. User intervention is required to Power Off/On the machine. Printing and other machine services are available.
We've already had multiple techs out over the past month, which have installed various SPAR releases (061.132.222.15103 to 061.132.222.28903), alt-booting, manually config (vs using a cloning file), replaced network controller hardware, etc. They've seen this exact error message on other different model WorkCentre devices across this facility too, which makes be believe someone has figured out an exploit for this class of printer.
To be honest your best way here is to follow the support line with network traces, ESS logs and audit logs. Provide it all for a quicker resolution time..
Like I mentioned if its the service failing on the device than is not much you will be able to analyse. Unless network traces bring some light, such as lost packets, or overflush or snmp traffic that could cause the service to stop on the device.
