[Serusers] SER & SIPSAK: SER registration limitations

Friends, We are testing our SER set up using SIPSAK. Are there any limitations in terms of the number of registered subscribers that can be kept by SER in memory or in database? We tried with both db_mod 0 or 1. After some 40,000 registrations, SER starts Giving "No memory left" messages and sometimes terminates as well. And with db_mode=1, SER can not startup again, giving We checked the machine and out of 2GBytes of memory only about 10Mbytes Were used up. Any ideas? ramin ------------------------------------------------------------------------ ---------------- SER crash errors with db_mode= 0 or 1 ------------------------------------------------------------------------ ---------------- modparam("usrloc", "db_mode", 0) OR modparam("usrloc", "db_mode", 1) 12(24376) new_ucontact(): No memory left 12(24376) mem_insert_ucontact(): Can't create new contact 12(24376) insert_ucontact(): Error while inserting contact 12(24376) insert(): Error while inserting contact 12(24376) contacts(): Error while inserting record 12(24376) new_ucontact(): No memory left 12(24376) mem_insert_ucontact(): Can't create new contact 12(24376) insert_ucontact(): Error while inserting contact 12(24376) insert(): Error while inserting contact 12(24376) contacts(): Error while inserting record 19(24383) ERROR: tcpconn_new: mem. allocation failure 19(24383) ERROR: tcp_main_loop: tcpconn_new failed, closing socket 14(24378) Binding '2224449999335607','sip:2224449999335607@172.16.15.201:3006' has expired 14(24378) Binding '2224449999335608','sip:2224449999335608@172.16.15.201:3006' has expired 14(24378) Binding '2224449999335609','sip:2224449999335609@172.16.15.201:3006' has expired 14(24378) Binding '2224449999335610','sip:2224449999335610@172.16.15.201:3006' has expired 14(24378) Binding '2224449999127988','sip:2224449999127988@172.16.15.203:1815' has expired 12(24376) new_ucontact(): No memory left 12(24376) mem_insert_ucontact(): Can't create new contact 12(24376) insert_ucontact(): Error while inserting contact 12(24376) insert(): Error while inserting contact 12(24376) contacts(): Error while inserting record 19(24383) ERROR: tcpconn_new: mem. allocation failure 19(24383) ERROR: tcp_main_loop: tcpconn_new failed, closing socket 1(24365) 10(24374) INFO: signal 15 received 13(24377) INFO: signal 15 received 18(24382) 3(24367) INFO: signal 15 received INFO: signal 15 received 4(24368) 19(24383) INFO: signal 15 received 6(24370) INFO: signal 15 received ------------------------------------------------------------------------ ---------------- SER Startup error with db_mode=1 ------------------------------------------------------------------------ ---------------- And when I try with modparam("usrloc", "db_mode", 1) SER exits and to restart it, it gives me the following error and can't start: .
