Re: [libvirt] 'make check' hangs

When I run 'make check', it hangs sometimes. I use gdb to attach lt-virsh, and the following is the backtrace: (gdb) thread 1 [Switching to thread 1 (Thread 0x7fc6c04d5800 (LWP 24099))]#0 0x0000003bdce0804d in pthread_join () from /lib64/libpthread.so.0 (gdb) bt #0 0x0000003bdce0804d in pthread_join () from /lib64/libpthread.so.0 #1 0x000000000041c0b3 in vshDeinit (ctl=0x7fff015f4570) at virsh.c:17262 #2 0x00000000004248d1 in main (argc=<value optimized out>, argv=0x7fff015f4728) at virsh.c:17608 (gdb) thread 2 [Switching to thread 2 (Thread 0x7fc6c04d4700 (LWP 24138))]#0 0x0000003bdc2dc053 in poll () from /lib64/libc.so.6 (gdb) bt #0 0x0000003bdc2dc053 in poll () from /lib64/libc.so.6 #1 0x00007fc6c075359c in virEventPollRunOnce () at util/event_poll.c:619 #2 0x00007fc6c07527d7 in virEventRunDefaultImpl () at util/event.c:247 #3 0x000000000041bea3 in vshEventLoop (opaque=0x7fff015f4570) at virsh.c:16800 #4 0x00007fc6c0764702 in virThreadHelper (data=<value optimized out>) at util/threads-pthread.c:157 #5 0x0000003bdce077f1 in start_thread () from /lib64/libpthread.so.0 #6 0x0000003bdc2e570d in clone () from /lib64/libc.so.6 (gdb)
