zero byte extracting in PI

Hi Experts,

i have weird situation here. We have a scenario where we are using file receiver adapter on the receiver side. We are placing the files in PI folder and MQ is picking up the files from this folder. We are using dynamic configuration for the file name for this interface. What happens is sometimes MQ is picking up zero size files even though PI is sending data in the message. File adapter is creating the file name from dynamic configuration but unable to write the data in the file even though the message is having the data and we are unable to reproduce this scenario again. This happens only for few messages.

Can you please help me on how to solve this issue.

Thanks,

Srinivas.
