So maybe this is misleading and we have some issues with shared memory too small ? (just my wild guess) Uli Von: Herbst, Ulrich Gesendet: Freitag, 25.

We get this error message on a high-load-webserver: [proxy_http:error] [pid 13256:tid 47013272524544] (11)Resource temporarily unavailable: [client 172.31.0.142:21815] AH01110: error reading response And we have no clue, which resource is unavailable and what to do against it.

Any ideas how to find the reason for this error ?
