Thanks for the report. I was able to reproduce the problem using the pgpool binary and core file uploaded to the URL (for developers convenience, I uploaded the core file and the binary extracted from the compressed archive. It seems the bug was triggered when DB node 0 is disconnected (down status). Will fix. (gdb) bt #0 0x000000000041686e in pool_send_frontend_exits (backend=backend@entry=0x1fe77d0) at pool_process_query.c:995 0000001 0x000000000040c1ed in do_child (unix_fd=unix_fd@entry=5, inet_fd=inet_fd@entry=6) at child.c:423 0000002 0x00000000004075a1 in fork_a_child (unix_fd=5, inet_fd=6, id=349) at main.c:1271 0000003 0x0000000000407c27 in reaper () at main.c:2426 0000004 0x000000000040851d in pool_sleep (second=<optimized out>) at main.c:2623 0000005 0x0000000000406001 in main (argc=<optimized out>, argv=<optimized out>) at main.c:837 (gdb) list 990 */ 991 if (VALID_BACKEND(i) && CONNECTION_SLOT(backend, i)) 992 { 993 pool_write(CONNECTION(backend, i), "X", 1); 994 995 if (MAJOR(backend) == PROTO_MAJOR_V3) 996 { 997 len = htonl(4); 998 pool_write(CONNECTION(backend, i), &len, sizeof(len)); 999 } |
