Hey guys, I'm working on a simple media bug module using FS 1.6. When a call comes in I'm calling switch_curl doing an http get. In switch_standard_app I use switch_curl and invoke switch_curl_easy_perform and exit after that. Calling switch_curl seems very unstable. It's crashing free switch most of the time. Are there any things I should be looking for related to this? I'm wondering if maybe this is a threading issue? Any ideas? I've included some backtraces Thanks, chris (gdb) bt #0 0x00007f8f00c59cc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 #1 0x00007f8f00c5d0d8 in __GI_abort () at abort.c:89 #2 0x00007f8f00c96394 in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0x7f8f00da4b28 "*** Error in `%s': %s: 0x%s ***\n") at ../sysdeps/posix/libc_fatal.c:175 #3 0x00007f8f00ca266e in malloc_printerr (ptr=<optimized out>, str=0x7f8f00da0c19 "free(): invalid pointer", action=1) at malloc.c:4996 #4 _int_free (av=<optimized out>, p=<optimized out>, have_lock=0) at malloc.c:3840 #5 0x00007f8f01334567 in switch_log_node_free (pnode=pnode@entry=0x7f8eb2b1f158) at src/switch_log.c:136 #6 0x00007f8eeb192a24 in read_packet (listener=listener@entry=0x7f8ebc027898, event=event@entry=0x7f8eb2b1f7f0, timeout=timeout@entry=0) at mod_event_socket.c:1361 #7 0x00007f8eeb1988a0 in listener_run (thread=<optimized out>, obj=0x7f8ebc027898) at mod_event_socket.c:2719 #8 0x00007f8f01544430 in dummy_worker (opaque=0x7f8eb2be4868) at threadproc/unix/thread.c:151 #9 0x00007f8f00ff0182 in start_thread (arg=0x7f8eb2b20700) at pthread_create.c:312 #10 0x00007f8f00d1d47d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111 *[* <https://soniccloud.slack.com/archives/D02UEC39S/p1458078254000027> 5:44 <https://soniccloud.slack.com/archives/D02UEC39S/p1458078254000027> *]* <https://soniccloud.slack.com/archives/D02UEC39S/p1458078254000027> (gdb) bt full #0 0x00007f8f00c59cc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 resultvar = 0 pid = 18329 selftid = 18421 #1 0x00007f8f00c5d0d8 in __GI_abort () at abort.c:89 save_stage = 2 act = {__sigaction_handler = {sa_handler = 0x0, sa_sigaction = 0x0}, sa_mask = {__val = {0 <repeats 16 times>}}, sa_flags = 0, sa_restorer = 0x0} sigs = {__val = {32, 0 <repeats 15 times>}} #2 0x00007f8f00c96394 in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0x7f8f00da4b28 "*** Error in `%s': %s: 0x%s ***\n") at ../sysdeps/posix/libc_fatal.c:175 ap = {{gp_offset = 40, fp_offset = 32654, overflow_arg_area = 0x7f8eb2b1f010, reg_save_area = 0x7f8eb2b1efa0}} fd = 2 on_2 = <optimized out> list = <optimized out> nlist = <optimized out> cp = <optimized out> written = <optimized out> #3 0x00007f8f00ca266e in malloc_printerr (ptr=<optimized out>, str=0x7f8f00da0c19 "free(): invalid pointer", action=1) at malloc.c:4996 buf = "00007f8ed0036700" cp = <optimized out> #4 _int_free (av=<optimized out>, p=<optimized out>, have_lock=0) at malloc.c:3840 size = <optimized out> fb = <optimized out> nextchunk = <optimized out> nextsize = <optimized out> nextinuse = <optimized out> prevsize = <optimized out> bck = <optimized out> fwd = <optimized out> errstr = <optimized out> locked = <optimized out> #5 0x00007f8f01334567 in switch_log_node_free (pnode=pnode@entry=0x7f8eb2b1f158) at src/switch_log.c:136 node = 0x7f8ed8012ab0 #6 0x00007f8eeb192a24 in read_packet (listener=listener@entry=0x7f8ebc027898, event=event@entry=0x7f8eb2b1f7f0, timeout=timeout@entry=0) at mod_event_socket.c:1361 dnode = 0x7f8ed8012ab0 do_sleep = <optimized out> mlen = 0 bytes = 0 mbuf = 0x7f8ecc1ebfc0 "" buf = "Content-Type: log/data\nContent-Length: 88\nLog-Level: 7\nText-Channel: 3\nLog-File: param_hps_strategy.cpp\nLog-Func: retrieve\nLog-Line: 115\nUser-Data: \347@ \247\a\n\n\000\n\n\000\065-418f-a6d1-9dc8f48e0cf9\n\n\000\000\071\n\n\000c8f48e0cf9"... len = 88 status = SWITCH_STATUS_BREAK count = 0 elapsed = <optimized out> start = 1457966137 pop = 0x7f8ed8012ab0 ptr = 0x7f8ecc1ebfc0 "" crcount = 0 '\000' buf_len = 2048 channel = 0x0 clen = 0 __PRETTY_FUNCTION__ = "read_packet" __func__ = "read_packet" #7 0x00007f8eeb1988a0 in listener_run (thread=<optimized out>, obj=0x7f8ebc027898) at mod_event_socket.c:2719 listener = 0x7f8ebc027898 buf = '\000' <repeats 1023 times> len = 1024 status = <optimized out> event = 0x0 reply = "\000OK log level [7]", '\000' <repeats 493 times> session = 0x0 channel = 0x0 revent = 0x0 var = <optimized out> locked = 1 __PRETTY_FUNCTION__ = "listener_run" __func__ = "listener_run" #8 0x00007f8f01544430 in dummy_worker (opaque=0x7f8eb2be4868) at threadproc/unix/thread.c:151 thread = 0x7f8eb2be4868 #9 0x00007f8f00ff0182 in start_thread (arg=0x7f8eb2b20700) at pthread_create.c:312 __res = <optimized out> pd = 0x7f8eb2b20700 now = <optimized out> unwind_buf = {cancel_jmp_buf = {{jmp_buf = {140250860095232, -640791540281233069, 0, 0, 140250860095936, 140250860095232, 578173923610734931, 577994035108262227}, mask_was_saved = 0}}, priv = {pad = {0x0, 0x0, 0x0, 0x0}, data = {prev = 0x0, cleanup = 0x0, canceltype = 0}}} not_first_call = <optimized out> pagesize_m1 = <optimized out> sp = <optimized out> freesize = <optimized out> __PRETTY_FUNCTION__ = "start_thread" #10 0x00007f8f00d1d47d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111 No locals
