All,
I cannot describe how thankful I am to Dmitry for figuring out this issue for
us.
I just had to spend 28 hours straight repairing database corruption due to this
error.
fstat call can return EAGAIN error when Linux kernel is under load.
This then leads to massive database corruption.
I believe this fix should be mentioned in WhatsNew.
