This started to happen after upgrade to `18.16.0` from `16.29.0`. Asterisk starting to spam logs with similar messages like:

After around ~3 minutes of these (Asterisk during that time is already unresponsive), we have final errors before service crush:

{code:none}
[2023-02-24 09:32:48.153] ERROR[11361] astmm.c: Memory Allocation Failure in function topic_add_subscription at line 1214 of stasis.c
{code}

And, from `/var/log/messages`:

{code:none}
Feb 24 09:32:48 localhost kernel: asterisk[11361]: segfault at 1 ip 0000000000552827 sp 00007f7ed3e0a6b0 error 4 in asterisk[400000+2a2000]
{code}

It happens randomly, once, twice a day, sometime doesn't happen at all.
Though, it's always happening when Asterisk is processing calls, so it's not happening during night (when asterisk is almost idle)
