I vaguely recall some issue with reuse when using unix socket files so it was deliberately set to off by default, but yes, perhaps someone experienced enough with mod_proxy_fcgi inner workings can shed some light on this and the why yes/not. With socket files I never tried to enable "enablereuse=on" and got much successful results, so perhaps it's safer to keep it off until someone clarifies this issue, after all when dealing with unix sockets the access delays are quite low. 2018-01-19 13:30 GMT+01:00 Stefan Eissing <stefan.eissing@xxxxxxxxxxxxx>: > Can someone with deeper proxy_(fcgi) knowledge than me jump in here.
