[OpenSIPS-Users] ERROR:usrloc:shm_str_dup: no shared memory left

[Josip Djuricic]

Hi,

 

I'm experiencing strange things with opensips (trunk). I'm testing it with
sipp to see how it's reacting to 100 000 user registrations.

 

For auth I'm using auth_aaa module with radius support, and mysql for
db_persistency.

 

So what I have noticed so far is:

If I test at rates of 40 registration per second with 100 000 unique users
(looping 100000 registrations over and over), and expiry time of 3600secs,
everything works fine, because there is no expired and opensips don't have
to delete anything from db and memory. Memory is constant according to ps,
free and top

 

But if I use 20min registration expire time, after some time(740841
registration request sent) I get:

Since I am just registering same contacts like before I wonder why this
happen?

 

It seams to me that expired contacts doesn't get deleted from memory? So SHM
is constantly rising? Is there anyway to check if this is the case?

 

Also I'm starting opensips with -m 128 and I've changed private memory to
16*1024*1024 so that it can read 100000 contacts from db when starting.

 

I'm using default configuration for test, just added db and radius support.

 

Any ideas?

 

Perhaps I should move to stable v1.6?

 

Thanks,

 

Josip
