Re: iotest40 problem

[Li Zhang]

Hi,

I backport some iotests patches to the tree and change timeout.
It doesn't work.

Sometimes, iotest41 also reports the errors.

I can see other errors like this, it's the problem of the socket.

[ 1535s] socket_accept failed: Resource temporarily unavailable
[ 1535s] **
[ 1535s] 
ERROR:../tests/qtest/libqtest.c:321:qtest_init_without_qmp_handshake: 
assertion failed: (s->fd >= 0 && s->qmp_fd >= 0)


The script is running the command as this:
/usr/bin/make -O -j4 check-block V=1

I can see the errors on ppc, arm or x86.
But I couldn't reproduce it when I run it manually.

It will be appreciated if any suggestions. Thanks.
