ModemManager --debug

Hi,
I am getting the following debug output on a Quectel UC20 modem, using ModemManager version 1.6.10 (see attachment debug.log)

Does this happen just after boot? Or does this happen e.g. after several suspend/resume cycles?

Hi,
this happens at boot time.
Comment 5 samentu1 2017-11-13 04:19:31 UTC
Hi Aleksander, do I need to provide additional logs for helping debugging?
Comment 6 Aleksander Morgado 2017-11-13 08:37:03 UTC
Unfortunately none of the last logs provided show the ClientIdsExhausted issue... Anyway, I'm thinking that it may not be a bad idea to run a explicit "sync" operation any time the qmi-proxy starts, because that would flush any previously allocated and not released client id.

The weird thing, though, is that this happens during boot time, so there shouldn't be any client id allocated previously.

Yes, running qmi-network was done after MM was not able work just to see if it's something on MM's side or not.
Comment 8 samentu1 2017-11-13 13:21:16 UTC
Sorry for the previous message (badly written)
I had ran qmi-network after seeing that MM cannot manage the modem.
The ClientIdsExhausted is showing up at boot, without ever running qmi-network before.
What other logs could I supply? I have a different Quectel modem that is behaving in a similar fashion, so I can supply needed logs from this other one too.
