INFORMIX SERVER / 5725A3900 / E10 - |
| Problem description: |
Shortly after bringing the server on-line, it's possible for the
server to assert with a stack like below when
running set explain off.
0x00000000014e501d (oninit) afstack
0x00000000014eabe1 (oninit) mt_ex_throw_sig
0x00000000014f8d68 (oninit) afsig_handler
0x00007fa64fe205e0 (Linux)
0x00000000014cc299 (oninit) mt_aio_fclose
0x0000000000646a84 (oninit) setexplain
0x00000000007502de (oninit) aud_setexplain
0x0000000000640bd7 (oninit) excommand
0x0000000000af260b (oninit) sq_execute_workhorse
0x0000000000af2e4d (oninit) sq_execute
0x0000000000bc655e (oninit) sqmain
0x0000000001613a7a (oninit) spawn_thread
0x00000000014d5cf2 (oninit) th_init_initgls
0x000000000151c00f (oninit) startup
The problem has a generally reliable reproduction, but after it
asserts for the first time on a cpu vp
it seems to no longer reproduce. |
