[mod-security-users] modsecurity pause action seems to be causing request to be dropped

[Paul B. <pau...@ou...>]

Yesterday this seemed to be working for me, but today this rule is seems to be causing the request to be dropped

Rule:
SecRule REQUEST_URI "@rx ^/slow/page" "id:2003,phase:2,nolog,noauditlog,pause:371"

If I comment it out page returns, uncommented curl comes straight back with:
* Empty reply from server
* Connection #0 to host modsectest.local left intact
curl: (52) Empty reply from server

This is being tested against a simple newly built test environment:
Ubuntu 18.04.3 LTS
Apache2 and mod-sec installed from repository
Loading CRS3

If anyone can see an obvious explanation for this, I'd be very grateful.
Thanks,
Paul
