[proxy_fcgi:error] AH01071

Mostof my sites are working fine. But one of the sites throughs this error

[proxy_fcgi:error] [pid 107694:tid 107699] [client 46.243.3.42:58152] AH01071: Got error 'Primary script unknown'

If I reboot server, sites works again for few hours

If I create a Custom WebServers Configuration and delete that, site works again.

Please suggest

Looks like the issue is due to infection discussed here

That's a definite possibility; did you sanitize your known infections? Here's a quick-n-dirty way using the locate DB (which may not be current, but should be within 24 hours):

Code: [Select]

rm -if $(locate defauit.php) && rm -if $(locate nbpafebaef.jpg)But another possibility is erroneous permissions on the user account in question. Can you run the User Accounts -> Fix Permissions routine?
