The memory allocation of Asterisk 11 seems to constantly increase.
Specifically, the cache allocated in frame.c seems to increase without bound. I haven't let it go this far, but it seems it would likely max out system memory and be killed by the OOM killer.

$ asterisk -rx "memory show summary" | sort -rn
3950471103 bytes allocated (3923172359 in caches) in 5289609 allocations
3922949255 bytes (3922882279 cache) in    5184358 allocations in file frame.c
..

$ asterisk -rx "core show channels"
8 active channels
4 active calls
14745 calls processed

$ asterisk -rx "core show uptime"
System uptime: 2 days, 14 hours, 17 minutes, 32 seconds 
Last reload: 2 days, 14 hours, 17 minutes, 32 seconds
