[Serusers] Getting online users out of SER

Hi, I am currently testing SER for running it in a quite large environment with about 40000 online users. I'd like to offer my users an online/offline status - at least for themselves, maybe also for users in their contacts. I have noticed that when operating SER in database mode every time it writes back the location to database it hangs and doesn't answer requests anymore. This situation is not acceptable, whenever this happens no REGISTERs, INVITEs, 200OKs or anything else passes the server and registering fails, calls don't get established a.s.o. I think a lot of you have an online/offline status, but which way do you go technically? One way would be to grab the contacts from the FIFO, but that solution doesn't seem to be suitable, too. The problem with that is, that only one process at a time can query the fifo, and at this time, other processes will hang, you'll have to start the query once again. I played around with the click2dial script and other fifo stuff and noticed how error-prone that is. Once the fifo didn't answer at all anymore and I had to restart SER. Is anyone running another solution for getting all or some contacts out of SER? Thanks in advance, Sebastian -- Sebastian Damm GPG-Encrypted mail welcome!
