[Users] uac_redirect out of memory?

Hello,

if you get "out of memory" at peak and then it recovers, it is not a 
memory leak, just insufficient shared memory. Use -m command line option 
to tune the value. By default it is 32MB.

The size of memory you have to allocate depends on how many subscribers 
online you have. The user location cache uses shared memory as well.

Cheers,
Daniel
