Hi Daniel,

In a scenario in witch we have a winfo and presence Subscribe with a 70 sessions per second after a wile (3906 sessions in last test) the openser crashes. Can you take a look in the attached logs from /var/log/openser.log and from core dump (they are on the same attached file)?

Thanks, Toni

Hi Daniel,

Increasing the children from 4 to 16 did turn into same results (I was already using debug=3 and fork=yes).

But setting debug=0 did real turn in much better results.

looks like lot of syslog messages are printed. Can you check if your syslog is set asynchronous for openser?

Cheers, Daniel

Thanks a lot, Toni

Hello,

if you use exactly the same config, then turn debug to a lower level (e.g., 3), set fork=yes and children to 16 for better results.

Cheers, Daniel

Hi Anka,

In a scenario using Openser as a Presence Sever (using the config file example located in http://openser.org/dokuwiki/doku.php/presence:configuration-file), the execution of load tests (with sipp) with Subscribe Presence WInfo had as result a maximum of 20 sessions per second (We are using a Intel(R) Xeon(TM) CPU 3.00GHz with 2GB RAM), with lots of retransmissions if we increase to values bigger than 20 (Openser dos not crash). Is there any configurable parameter in the Presence module that allows increasing this value?

Best regards,

Toni
