Description Craig 2017-08-04 13:18:59 UTC
When there are concurrent HTTP/2 requests, Apache hangs processing a request and log "h2_task.c Software caused connection abort"

This is immediately noticeable when attempting to access the Wordpress Admin dashboard - but that is only an example, this issue occurs in many other cases as well.

This issue has been reported to and fixed in mod_h2: https://github.com/icing/mod_h2/issues/143

This issue does not occur in 2.4.26, and does occur in 2.4.27.
