We have a customer where their VM running Asterisk appears to have crashed. Fortunately, we had some debugging enabled. The asterisk messages file has this... (in notepad+ the blank line in the middle is all [NUL][NUL] [NUL][NUL]....)

We also had debugging enabled and things were output to our debug file for 17
more seconds....
The blank line in my e-mail is once again a line with all [NUL}... (in notepad+
the blank line in the middle is all [NUL][NUL] [NUL][NUL]....)

[Aug 12 15:33:02] DEBUG[1385] config.c: Parsing /etc/iss/asterisk/logger.conf
I believe this was bad enough that Ubuntu actually crashed, but there is
nothing in the syslog indicating anything until 15:32:42 where it appears Linux
is starting up.
After this situation happens, every time Asterisk starts up, it was taking
significantly longer to load. Normally 1-2 seconds, became 26-28 seconds.
[08/12 15:33:03.240] NOTICE[1385] loader.c: 286 modules will be loaded.
[08/12 15:33:23.844] VERBOSE[1385] loader.c: Loading extconfig.
Loading the modules is taking 20 seconds after this incident occurred. Looking
at the debug logs, I see the modules loading loader.c PASS. There all seem to
load fine, just much slower than it was previously.
Any suggestions on where to look for a cause of things running slow after this?
