The last time it happened, I issue 'iax2 show callnumber usage' and it shows that I am out of Regular callno:

I do not know if this is relevant, but there a kernel message which seems suspicious to me:

[499321.365191] traps: asterisk[17039] trap invalid opcode ip:7fb46af2dedc sp:7fb3e4c0b890 error:0 in libpthread-2.23.so[7fb46af21000+18000]

Function get_unused_callno issues "Out of call numbers"
And Function __find_callno issues "No more space" if the former fails
So this is no usual out of (disk) space or such.

I'm really no asterisk expert but there are two cases:
a) you are really out of numbers (not a bug, just as it is)
b) asterisk thinks you are out of numbers due to a bug e.g. not freeing unused correctly

Could you confirm that we are looking at (b) in this case?

Also how easily is this reproducible for you?
If you can kind of intentionally trigger it I'd recommend you might try one of the newer versions available in newer Ubunutu releases - if those work reliably that might confirm that there already is a fix in the asterisk project that we have to look for to backport.

For the illegal opcode - there are (to my surprise) several of those issues found by search engines. Those issues usually are super rare - only if either the code is totally wrong, compiled against wrong libs/headers or virtual machines which do not provide all expected cpu features.

It sounds similar to [1], but that code is in the version you run.
Also [2] is similar but very old as well.
Maybe you find some tests/workarounds there still?

TL;DR - as unfortunate as it is for now I can't differ this between a bug or a config issue.
Waiting for your feedback - hopefully this is somewhat reproducible to be debuggeble by you.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.

Changed in asterisk (Ubuntu):
