Summary:                    [patch] Memory leak in manager.c
Description: 
I detected a memory leak in manager.c, on latest Asterisk 1.6.2.7-rc2.
Leak is reproductible in 1.6.2.6.

   6622144 bytes in 30993 allocations in file 'manager.c'
   7100873 bytes in 33065 allocations in file 'manager.c'
   7352505 bytes in 34160 allocations in file 'manager.c'
   7636791 bytes in 35405 allocations in file 'manager.c'
   8039968 bytes in 37165 allocations in file 'manager.c'
   9430346 bytes in 43322 allocations in file 'manager.c'

I'm sending Originate (async) AMI commands using the built-in HTTP
server.

Attached: valgrind run with --leak-check=full --show-reachable=yes, and
"memory show allocations". Asterisk was compiled with MALLOC_DEBUG and
DONT_OPTIMIZE.

Eliminate stale manager events after a set interval, even if AMI clients
don't query for them.

Actions (or failures to act) by external clients should not cause memory
leaks
in Asterisk, especially when those continued leaks could cause Asterisk to
misbehave later.
