Charles Day commented on ASTERISK-17163:
----------------------------------------

I can also confirm this bug in the {{pbx_spool.so}} module of Asterisk 10.8.0 running under OSX 10.8.2 (Mountain Lion).

The 100% CPU occurs when {{pbx_spool.so}} is loaded by modules.conf. Without {{pbx_spool.so}}, CPU usage is only about 0.9%.

However, I tried adding the code suggested by John Papandriopoulos to {{pbx/pbx_spool.c}} and rebuilding (make clean, make, sudo make install). It didn't seem to help, as CPU usage was still 100%.

> I've run Asterisk 1.8.0 and 1.8.1 on several Macs (all running Mac OS X 10.6.5) and in every case it sucks up 100.x% of available CPU.  (Note that in call cases the system has at least 2 cores, so this is possible).  I've run a profile (or what the Mac calls a "sample") and it shows a lot of this:
