[Users] load testing presence server

[Toni Barata]

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

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

Cheers,
Daniel
