That's not surprising, that's Apache calling/forwarding to starman (we're not using a socket, I don't remember why)

(and we've how updated the config to have 127.0.0.1:5000 instead of localhost

A reverse proxy running on localhost:5000...???

Hello,

We have a library running Koha (17.11) on his own centOS (virtual) server, with Apache as webserver.

Everything is working smoothly, except that, from time to time (about once a day), it's not working anymore, any page returns: "Proxy error, Error reading from remote server"

The logs shows nothing except a strange:

 [Wed Jul 10 17:17:35.732798 2019] [proxy_http:error] [pid 322] (70007)The timeout specified has expired: [client 1.2.3.4:32988] AH01102: error reading status line from remote server localhost:5000, referer: https://xxx.xxx.xxx.fr/cgi-bin/koha/catalogue/detail.pl?biblionumber=78504&searchid=scs_1562770062842

What is stranger : after a few minutes, without any action on the server, everything is back, and working well.

did anyone face such a problem ? any idea welcomed !
