Can't restore not-sent send queue data (-1), want (0-592:2427144:592): Broken pipe

[Tianyang-Zhang]

Description

I'm trying to checkpoint restore a pretty complicate program that involves R and something else. Sometimes I hit the Can't restore not-sent send queue data (-1), want (0-592:2427144:592): Broken pipe error after some run time. Could anyone please give some idea in what situation this error could happen? I am using the --tcp-establish flag for both checkpoint and restore. Any other option I should try? Thanks!
