Bug #3566
Updated by Dan Mick over 11 years ago
Investigating other things entirely, I had set log max err = 1 in [global]; I started observing occasional hangs, and could not explain; instrumenting a loop of @while "while true; rbd rm <nonexistent; done@ done", I noticed the hang after rbd finished the last statement of the Rados destructor, which is the last thing I could think to instrument. gdb got garbage and uninterpretable stacks. I found the log setting by accident. I suspect some kind of memory corruption with the Log destructor racing against log calls, but that's only based on a half-analysis of the problem, not any actual evidence.
