Hello,
I'm testing with kamailio 1.4 (just got revision 5050). I'm stressing it using a sipp scenario to verify which population of subscribers kamailio can handle.
Using openser 1.3.3 I could easily keep thousands of subscribers online even when running on a VirtualMachine hosted on a desktop computer (last time I tested this it was about 8000 subscribers).
But I'm running kamailio on a production machine and when I reach around 700 subscribers, kamailio starts to log this:
Oct  9 17:44:20 ipx029 /usr/local/sbin/kamailio[7689]: ERROR:auth:build_auth_hf: no more nonces can be generated
Oct  9 17:44:20 ipx029 /usr/local/sbin/kamailio[7689]: ERROR:auth:challenge: failed to generate nonce
And the registration fails.
Is anybody else seeing this?

regards,
takeshi
