build my own database-backended storage system that all Opensips processes,

this is not a lightweight solution and I’m certain it will require a
beefy database server as we get larger, but it was the only way I could see to
make it happen…<o:p></o:p></span></p>

<p class=MsoNormal>Hey all,<o:p></o:p></p>
<div>
<p class=MsoNormal>I'm wondering if there is a way to use global variables? I
see that $var variables are persistent across the process, but I need something
that will persist across all processes. Right now, I'm using memcache, but I'm
not sure if I'll have race conditions relying on that as I expect many
processes to be accessing and updating the globals for every call.<o:p></o:p></p>
