Pipelines failing with read time error on pipeline execute snap


our production pipelines are facing a severe impact after 4.19 upgrade.
we saw lot of pipelines are failing with read timeout error :

this kind of error was not observed during 4.18 or previous versions and it started coming very frequently after 4.19 update. our infra setting has not changed recently and still we are getting this issue. we suspect something has been done in 4.19 which is causing this issue. can u let me know the details?

Probably best to open a ticket with support.
