CMX just stopped

[HansR]

Without any message CMX was out this morning (see logfiles, no debugging was switched on).

The only exception I can think of was the fact that the Linux machine had been running for 6 weeks and three days straight which had been a first.
No message even no indication of what had happened so this is just a report (I am not going to run DEBUG for 6 weeks: I just accept a reboot)

In addition the journald just told me - after the dotnet start - for CUtils, to completion - at 03h21 i get:

Code: Select all

mei 30 03:21:17 rpiCMX3 dotnet[10813]: Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

From the logfiles I can see :

• that CMX stops logging after "2024-05-30 03:20:01.366 Reading sensor ids"
• that CUtils starts without a problem at 2024-05-30 03:21:02.475 and runs until 2024-05-30 03:21:14.496

There are no other indications of error in the journal afaics so it seems dotnet is the culprit somewhere in CMX.

NOTE: I run CMX for no longer than a day because of backup procedure after which I restart. This had been going OK for 6 weeks 3 days.

It does look like a crash in dotnet rather than Cumulus

Agree... Dotnet seems the culprit.
But since I seem to be the first and only it does not seem to be a big deal.

OK... I am curious

There does seem to be a dotnet 8.0.106 released on 28th may. Not sure if it's available for Linux packages as yet

Since I like being on the "bleeding edge" as Hans knows I installed .NET 8.0.6 and CumulusMX 4 is up and running on it on Windows 10.

Tried to find out what had changed and it seems to be memory components mainly. Perhaps after 6 weeks you ran out of memory or hit a memory limit?

@hvd51: ok. Question is: did CMX ever stop abruptly in this almost 7 week period? I see it has been running for 16 hrs now, so did it crash 16 hrs ago? (I assume not )

[hvd51]

@Hans,

No I stop cumulusmx for the backup every night at 00.36 (Your script).

Ok. Thnx. So everything is OK.
Good
