[SR-Users] Kamailio crashing when accessing db tables

Hi, I installed the latest version 4.0 on CentOS release 5.9 , and when running any fifo command that accesses a module's table (lcr, address etc.) or when a call comes in an there is a need to access a table the app crashes. Example: Jul 23 09:07:55 proxy01 kernel: kamailio[16608]: segfault at 0000000000000000 rip 00002b3bcd39a36c rsp 00007fff28ef40d0 error 4 Jul 23 09:07:55 proxy01 ./kamailio[16565]: ALERT: <core> [main.c:788]: handle_sigs(): child process 16608 exited by a signal 11 Jul 23 09:07:55 proxy01 ./kamailio[16639]: : <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 41 Jul 23 09:07:55 proxy01 ./kamailio[16565]: ALERT: <core> [main.c:791]: handle_sigs(): core was generated has any one seen this? Is there something new on this version that I am missing? thank you a lot fabian
