[Serusers] ERROR: nathelper::timer: out of memory

Hi,

maybe someone can help me with this Problem.

Actually we have 300 Users in our location table, having nat_flag = 4;

Servermemory:

total used free shared buffers cached Mem: 1029208 971552 57656 0 115460 572440 -/+ buffers/cache: 283652 745556 Swap: 996020 6300 989720

System: Debian 2.4.24 Ser: sip_router_0.8.12_stable

# -- nat Params modparam("nathelper", "natping_interval" , 20) modparam("registrar", "nat_flag", 4)

every 20 Seconds I have the Error in SYSLOG: ERROR: nathelper::timer: out of memory

I found the Error message in the ser/modules/nathelper.c code but i am not really a c programmer.

any ideas?

Best Regards, Markus
