It probably needs a fix like below because mod_init has also created a db
connection which is inherited by at least one child and ul_dbh is not 0 anymore.
That process needs to be excluded from opening a database connection, all
other childs need to open their own DB connection. I just don't know what
rank mod_init is run as and thus don't know which process to exclude. Maybe
some other dev can jump in.

Hi,
Your patch didn't work for me. The kamailio didn't start if i use "if (
_rank != PROC_MAIN)"
So i commented out, both if statement, and now "out of sync problem
disappeared"

That should do the trick, but it might be possible to create a
zombie
connection this way. I don't know how the initialization of modules works
exactly, so I can't really help you with this.
BUT
I am experiencing that in usrloc module, still more then one worker
process share the same sql connection:
That is weird. AFAIK, connections can't be shared between processes, there
seems to be no locking/semaphores/whatever to protect against simultaneous
access.
Maybe you got lucky in your tests and just didn't have enough traffic to hit
the simultaneous access problem (yet).
I'm out of ideas here, sorry.

I'm sorry, the first patch was totally bogus. Due to the forking of the
childs, they have the same memory layout and a very high chance of allocating
the same address (in their own address space) for the connection struct.
Attached patch should give a thread_id truly unique per connection. If you're
able to find multiple processes using the same thread_id, you've found the
cause.

Attached patch should give a thread_id truly unique per connection. If you're

Hi,
With this debug i can see that all tcp connections are using the same db
connection(18549).
Any suggestion highly appreciated!

So the problem is that rank: 0 PROC_MAIN process initialitzed and have
db connection with mod_child_init,
and after rank 0 PROC_MAIN process is forking for tcp workers it
contains the initialized ul_dbh and no unique connection created for the
tcp workers.
Any suggestion, solution?
Thanks,
Misi

Any suggestion, solution?

Hi,
With this debug i can see that all tcp connections are using the same
db connection(18549).
Any suggestion highly appreciated!

Hi Daniel,
Thank You for your reply!

Are you sure that it will not cause any problem that rank -1 process in
usrloc database will be initialized twice, and ul_dbh will be overloaded
with new connection?
I guess this will cause problem.

I guess this will cause problem.
it is safe, we have connection pool system inside,
allowing many modules
to use the same db connection when the db url value is matched. So, if a
connection with same db url exists, it will be reused.
Cheers,

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users So the problem is that rank: 0 PROC_MAIN process
initialitzed and
have db connection with mod_child_init,
and after rank 0 PROC_MAIN process is forking for tcp workers it
contains the initialized ul_dbh and no unique connection created for
the tcp workers.
Any suggestion, solution?
Thanks,
Misi

Hi,
With this debug i can see that all tcp connections are using the
same db connection(18549).
Any suggestion highly appreciated!
Please read collected information on the bottom of my email.

Hi Daniel,
Thank You for your reply!
- if (!ul_dbh)
- ul_dbh = ul_dbf.init(&db_url); /* Get a new database
connection */
+ ul_dbh = ul_dbf.init(&db_url); /* Get a database connection
per child */
Are you sure that it will not cause any problem that rank -1 process
in usrloc database will be initialized twice, and ul_dbh will be
overloaded with new connection?
I guess this will cause problem.
it is safe, we have connection pool system
inside, allowing many
modules to use the same db connection when the db url value is
matched. So, if a connection with same db url exists, it will be reused.
