Leif Hedstrom reassigned TS-942: -------------------------------- Assignee: (was: Leif Hedstrom) > Assert in HttpTransact::HandleCacheOpenReadMiss > ----------------------------------------------- > > Key: TS-942 > URL: https://issues.apache.org/jira/browse/TS-942 > Project: Traffic Server > Issue Type: Bug > Components: HTTP > Affects Versions: 3.1.1 > Reporter: Leif Hedstrom > Priority: Critical > Fix For: 3.1.2 > > > I'm seeing a crasher (see below), and it happens in code like this: > {code} > if (s->current.server->ip == 0) { > ink_release_assert(s->current.request_to == PARENT_PROXY || > s->http_config_param->no_dns_forward_to_parent != 0); > if (s->current.request_to == PARENT_PROXY) { > {code} > What happens is that .server->ip is indeed 0, but current.request_to is != > PARENT_PROXY (it is instead ORIGIN_SERVER). I've not seen this before, and it > reproduces rarely, so wondering if it could be IPv6 related. > Crasher: > {code} > (gdb) bt > #0 0x0000003f2de327f5 in raise (sig=6) at > ../nptl/sysdeps/unix/sysv/linux/raise.c:64 > #1 0x0000003f2de33fd5 in abort () at abort.c:92 > #2 0x00000000006407a1 in ink_die_die_die (return_code=<value optimized out>, > message_format=<value optimized out>, ap=0x2b0756137600) at ink_error.cc:43 > #3 ink_fatal_va(int, const char *, typedef __va_list_tag __va_list_tag *) > (return_code=<value optimized out>, message_format=<value optimized out>, > ap=0x2b0756137600) at ink_error.cc:65 > #4 0x00000000006408d6 in ink_fatal (return_code=<value optimized out>, > message_format=<value optimized out>) at ink_error.cc:73 > #5 0x000000000063f761 in _ink_assert (a=0x668400 "s->current.request_to == > PARENT_PROXY || s->http_config_param->no_dns_forward_to_parent != 0", > f=<value optimized out>, l=2952) at ink_assert.cc:44 > #6 0x0000000000516d5c in HttpTransact::HandleCacheOpenReadMiss > (s=0x2b0763638018) at HttpTransact.cc:2952 > #7 0x00000000004f08e2 in HttpSM::call_transact_and_set_next_state > (this=0x2b0763637fb0, f=<value optimized out>) at HttpSM.cc:6339 > #8 0x00000000004fffda in HttpSM::handle_api_return (this=0x2b0763637fb0) at > HttpSM.cc:1520 > #9 0x00000000004f2d42 in HttpSM::state_hostdb_lookup (this=<value optimized > out>, event=<value optimized out>, data=<value optimized out>) at > HttpSM.cc:2064 > #10 0x0000000000503de0 in HttpSM::main_handler (this=0x2b0763637fb0, > event=500, data=0x2b0760231860) at HttpSM.cc:2454 > #11 0x000000000058d07b in handleEvent (cont=0x2b0763637fb0, > ar=0x2b0760231860) at ../../iocore/eventsystem/I_Continuation.h:146 > #12 reply_to_cont (cont=0x2b0763637fb0, ar=0x2b0760231860) at HostDB.cc:552 > #13 0x000000000058e939 in HostDBContinuation::dnsEvent (this=<value optimized > out>, event=<value optimized out>, e=<value optimized out>) at HostDB.cc:1504 > #14 0x000000000059d281 in handleEvent (this=0x2a1c340, event=<value optimized > out>, e=<value optimized out>) at > ../../iocore/eventsystem/I_Continuation.h:146 > #15 DNSEntry::postEvent (this=0x2a1c340, event=<value optimized out>, > e=<value optimized out>) at DNS.cc:1265 > #16 0x0000000000638204 in handleEvent (this=0x2b0755e36010, e=0x2a61090, > calling_code=1) at I_Continuation.h:146 > #17 EThread::process_event (this=0x2b0755e36010, e=0x2a61090, calling_code=1) > at UnixEThread.cc:140 > #18 0x0000000000638c7b in EThread::execute (this=0x2b0755e36010) at > UnixEThread.cc:189 > #19 0x0000000000637052 in spawn_thread_internal (a=0x1b206b0) at Thread.cc:88 > #20 0x0000003f2e6068e0 in start_thread (arg=0x2b0756138710) at > pthread_create.c:297 > #21 0x0000003f2dee0c9d in clone () at > ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 > #22 0x0000000000000000 in ??
