[sr-dev] Fwd: crash & 100% CPU usage problem with kamailio 3.1.2

Hi Andrei, Yes this is kamailio 3.1.2 code. I have put some DBG & LOG inside the tcp code to debug this problem that’s why the line number does not match. It happens frequently – you need to run stress for a day or more. We are using Microsoft OCS tools for the stress. Here’s a problem – it creates a circular linked list 0x00000000004e8d5b in _tcpconn_find (id=<value optimized out>, ip=0x7fff6d7393c0, port=5061, l_ip=0x7fff6d739280, l_port=0) at tcp_main.c:1491 (gdb) list 1486 #ifdef EXTRA_DEBUG 1487 DBG("a=%p, c=%p, c->id=%d, alias port= %d port=%d\n", a, a->parent, 1488 a->parent->id, a->port, a->parent->rcv.src_port); 1489 print_ip("ip=",&a->parent->rcv.src_ip,"\n"); 1490 #endif (gdb) print a $1 = (struct tcp_conn_alias *) 0x2aed7ed00220 (gdb) print *a $2 = {parent = 0x2aed7ed000e0, next = 0x2aed7ebfc568, prev = 0x2aed7ebfc568, port = 5061, hash = 2739} (gdb) print a->next $3 = (struct tcp_conn_alias *) 0x2aed7ebfc568 (gdb) print *a->next $4 = {parent = 0x2aed7ebfc428, next = 0x2aed7ed00220, prev = 0x0, port = 5061, hash = 2739} (gdb) print *a->next->next $5 = {parent = 0x2aed7ed000e0, next = 0x2aed7ebfc568, prev = 0x2aed7ebfc568, port = 5061, hash = 2739} (gdb) print *a->next->next->next $6 = {parent = 0x2aed7ebfc428, next = 0x2aed7ed00220, prev = 0x0, port = 5061, hash = 2739} (gdb) print *a->next->next->next->next $7 = {parent = 0x2aed7ed000e0, next = 0x2aed7ebfc568, prev = 0x2aed7ebfc568, port = 5061, hash = 2739} (gdb) print *a->next->next->next->next->next $8 = {parent = 0x2aed7ebfc428, next = 0x2aed7ed00220, prev = 0x0, port = 5061, hash = 2739} (gdb) print *a->next->next->next->next->next->next $9 = {parent = 0x2aed7ed000e0, next = 0x2aed7ebfc568, prev = 0x2aed7ebfc568, port = 5061, hash = 2739} (gdb) print c->aliases $10 = 3 Hope this helps. I have to check whether I have the core dumps . If I have I’ll send you. Regards -Zunnun
