 Hi bogdan,

  I mean the calls are cumulative calls.
 cumulative calls doesn't load ser. from ser point of view, the call is 
processed only when it's initialised and terminated. So, basically you 
can have as much active call as you want, without loading ser at all.
anyhow, it's an impresiv number of parallel call. It's a stress test or 
....? if it not, may I ask the number of registered user?

  I received the following error log
when it was down.

 looks like your ser gets into troubles because of insufficient private 
memory (default is 1M). Try to increase it in config.h, 
PKG_MEM_POOL_SIZE value (it's a define).
about the crash...excepting this log, do you have any additional info 
that will help us to track the problem down? no coredump is generated?

 Thanks a lot for your kindly help!

 Hi Kenny,

first what do you mean by 12000-15000 calls? established calls in 
parallel or calls that initiated in the same time? there is a huge 
diference.
second....what kind of failures? can you be a little bit more 
specific 
(even c'n'p from log will do it) third... when ser goes down.. there 
is no core dumped? no message in the log related to receiving a signal?..

regards,
bogdan
