Hi @chengweiv5 , sorry for responding that late.
Did you ever do a stack trace when this happens? You can do that by issuing a kill -3
or using the jstack
command. It is helpful if you get multiple stack traces so that we can compare what changed or didn't change in-between.
Maybe, all threads accepting requests are blocked.
thanks for your tips, @kolloch, we'll do that if we lucky to reproduce this issue.
We encountered this issue twice in about 3 months, generally we have about 25K jobs per day and the api server may doesn't response sometime. when this issue happen,
curl -X -L <host>:<port>/ping
will hang up for ever.
