<div dir="ltr">Hi,<div><br></div><div>I got the following error while running drbd-8.3.15,<br><div>kernel: drbd1_receiver: page allocation failure. order:4, mode:0x20<br></div><div><br></div><div style>and I also found some kernel tuning tips in this list.</div>

<div style>or kernel/drbd try to handle this situation automatically?<br></div><div style><br></div><div style>I saw the above error twice a day, </div><div style>and PID for receiver was the same number,</div><div style>
so I am wondering;</div><div style>- receiver thread was stopped, and try to restart</div><div style>or</div><div style>- receiver thread was not stopped, just suspend(waiting?)</div><div style><br></div><div style>How can drbd internal threads recover from this error?</div>
<div><br></div><div style>Thanks,</div><div style>Junko IKEDA</div></div>
