Message-ID: <AM6PR04MB5127C64E307526741697AF6D89550@AM6PR04MB5127.eurprd04.prod.outlook.com> (raw)

Hi,

I am running with spdk 18.10.3, and crashing during delete_nvmf_subsystem.
This happens pretty consistently (every 2-3 attempts) when I do the delete while the initiator is still connected.

I saw that bug #235 has the same stack trace as I am seeing, but I already have the fix.
I am digging into this, but would be glad to get some pointers as to where to start looking, or more specifically, how did you know to look into the lib/nvmf controller code according to this error.

This is my stack:
(gdb) bt
#0  0x00007f338ed46495 in raise () from /lib64/libc.so.6
#1  0x00007f338ed47c75 in abort () from /lib64/libc.so.6

#11 0x00007f338edfcbcd in clone () from /lib64/libc.so.6


I will open a bug on github for this once I collect all the information.
