Previous Comments: ------------------------------------------------------------------------ [2002-02-11 11:18:19] tcurdt@dff.st I replace the libphp4.so with an older version (4.0.4pl1 Build Date Mar 8 2001) and sybase_connect was back working. This seems to proof that the bug was introduced somewhere between 4.0.4pl1 and 4.1.1) Actually it looks like somwhow the closing of the connection is the problem. ------------------------------------------------------------------------ [2002-02-07 06:28:15] tcurdt@dff.st It's very strange sybase_pconnect works just fine but sybase_connect lets the child segfault (11) and die. I have done a strace and it looks like the connect works and data is transmitted. But at the end (doesn't matter if call sybase_close or not) the child dies. Here is the strace: [pid 23318] open("/opt/sybase/interfaces", O_RDONLY) = 5 [pid 23318] lseek(5, 0, SEEK_SET) = 0 [pid 23318] read(5, "orga-shops\n query tcp eth"..., 512) = 96 [pid 23318] open("/opt/sybase/locales/us_english/iso_1/libinsck.loc", O_RDONLY) = 8 [pid 23318] read(8, "\n; comment character is a semico"..., 512) = 512 [pid 23318] read(8, "kslash is the escape symbol.\n[la"..., 512) = 512 [pid 23318] close(8) = 0 [pid 23318] pipe([8, 9]) = 0 [pid 23318] fcntl64(8, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 [pid 23318] fcntl64(9, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 [pid 23318] socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 10 [pid 23318] setsockopt(10, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0 [pid 23318] setsockopt(10, SOL_SOCKET, SO_LINGER, [0], 8) = 0 [pid 23318] fcntl64(10, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 [pid 23318] connect(10, {sin_family=AF_INET, sin_port=htons(2635), sin_addr=inet_addr("217.6.225.82")}}, 16) = -1 EINPROGRESS (Operation now in progress) [pid 23318] select(11, [8], [10], [8], {60, 0}) = 1 (out [10], left {60, 0}) [pid 23318] connect(10, {sin_family=AF_INET, sin_port=htons(2635), sin_addr=inet_addr("217.6.225.82")}}, 16) = 0 [pid 23318] select(9, [8], [], [8], {0, 0}) = 0 (Timeout) [pid 23318] close(5) = 0 [pid 23318] getpid() = 23318 [pid 23318] send(10, "\2\0\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 512, 0) = 512 [pid 23318] send(10, "\2\1\0]\0\0\0\0\0\0\0\0\0\0\n\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 93, 0) = 93 [pid 23318] recv(10, "\4\1\0K\0\0\0\0", 8, 0) = 8 [pid 23318] recv(10, "\255\"\0\5\5\0\0\0\30Adaptive Server Anywher"..., 67, 0) = 67 [pid 23318] send(10, "\17\1\0!\0\0\0\0!\24\0\0\0\0SELECT * from dumm"..., 33, 0) = 33 [pid 23318] recv(10, "\4\1\0,\0\0\0\0", 8, 0) = 8 [pid 23318] recv(10, "\356\23\0\1\0\tdummy_col\20\7\0\0\0008\0\321\0\0\0\0\375"..., 36, 0) = 36 [pid 23318] send(10, "\17\1\0\n\0\0\0\0q\0", 10, 0) = 10 [pid 23318] recv(10, "\4\1\0\21\0\0\0\0", 8, 0) = 8 [pid 23318] recv(10, "\375\0\0\0\0\0\0\0\0", 9, 0) = 9 [pid 23318] --- SIGSEGV (Segmentation fault) --- <... select resumed> ) = ?
