Max number of connections?

App_rpt-users
1

My node just crashed at the beginning of a net that my node hosts. Checking the logs the only thing I can see is a warning in /var/log/asterisk/essages.1 that says WARNING[445] app_rpt.c: maximum number of links exceeds 32 in rpt_do_stats()!

Is there a hard limit to the number of connections in asterisk (bandwidth is not an issue on my end)? I probably had maybe 40 nodes connected at the time.

Thx.

This may be related to my problem:
https://github.com/AllStarLink/Asterisk/issues/40

But I welcome comments from the community. As context, I am running Asterisk on Debian 10 using an x86 VM.

This might be a HamVoIP limitation as I’ve never heard of it with ASL.

4

Good to know. I am running asterisk on this node so am curious if anyone knows what the consequence of the warning message above might be.

5

Are you using a newer version of app_rpt -ASL on debian or a older version like ACID on centos ?

6

New version for Debian (I am running Debian 10) that works on x86 VMs.

In case it is helpful, here is the log output that was generated the moment app_rpt crashed this weekend when I had around 40 nodes connected to it:

The answer apparently is in the link you discovered.

look for this in the source code app_rpt.c
#define MAX_STAT_LINKS 32

change it to

#define MAX_STAT_LINKS 128 (or 64)

recompile the source code.

I believe the number is for directly connected links and not downstream.
My memory is lost but I thought this was definable in globals in acid.
