[Freeswitch-users] max-sessions change when running about 2 hr

[Dome Charoenyost]

Dear sir,
   I'm running freeswitch with option
/opt/freeswitch/bin/freeswitch -nf -waste -nonat -nc
I'm setting up max-sessions in switch.conf to 10000

    <param name="max-sessions" value="10000"/>
    <!--Most channels to create per second -->
    <param name="sessions-per-second" value="50"/>
But when fs running about 2 hr. max session down to 299
freeswitch at internal> status
UP 0 years, 0 days, 2 hours, 11 minutes, 10 seconds, 434 milliseconds,
251 microseconds
20502 session(s) since startup
271 session(s) 0/50
299 session(s) max

Can somone tell me what's happen ?

Dome C.
