• Does the crash happen with 1.13 ?
• Have you compiled your code with -race and ensured there are no races ?
• Is this issue reproducible ? Can you share with us a sample code that causes the crash ?

[benshi001]

Add an extra USB disk and mount is as swap? I had a similiar issue and the extra swap fixed it.

[jshachm]

we met this panic when we use containerd
@mmli519 anyother info update？

--- not use 1.13 in product environment yet

• Have you compiled your code with -race and ensured there are no races ?

--- no, we will try use -race in dev environment

• Is this issue reproducible ? Can you share with us a sample code that causes the crash ?

--- still not reproduced? not sure which code causes the crash

thanks, I think it should not be caused by swap.

not yet, still investigate the crash
