This could possibly due to quiesce option enabled. or , To avoid this issue, disable the SYNC driver or stop the service generating heavy I/O before taking a snapshot. Under heavy loads, the delay in I/O can become too long, which affects many time-sensitive applications, including the services which generate the heavy I/O (such as an Exchange Server). If writes issued by these services get delayed for too long, the service may stop and issues error messages.
