The I/O operations on my client system often encounters I/O errors,

information from local hard drive?
Two things:
1. Check the logs. Typically, I would expect such errors in low-level
filesystem driver code to log the error somewhere.
2. It could be that your client is buggy. For example some calls return
EAGAIN when they are interrupted by something. That is a recoverable
failure and you should just try again. I'm not sure if that is the case
here, but I'd track down the calls that fail and read the manpage very
closely.
