Hi Michal, Thanks for your review. The problem occured in a python applicatin using libvirt-python, which has no ref(). If we unref() first in virKeepAliveTimer, we may get a segfault in virObjectUnlock() when cleanup, so I suppose that my patch is safer, :-) Here is the backtrace:
Okay, now it makes more sense. However, the ref() I was referring to is our libvirt virObjectRef() not the one in python. The code where segfault occurs is too deep for python to see anyway. One thing that I am still worried about is doing virObjectRef() before virObjectLock(). I think these two steps should be swapped.
Can you check please whether that also fix your problem when you switch those two lines?
