Topic: Randomly receive 502 Bad Gateway error (Apache 2.4.4)

[hyohannes]

Hello all,


I am currently running apache 2.4.4 with Tomcat and randomly i receive the following error when i try to hit the external URL:

Bad Gateway
The proxy server received an invalid response from an upstream server


====================================================
Inside apachie error.log file., i also see the following error, i am not sure if they are related:

"The specified network name is no longer available. : AH00341: winnt_accept: Asynchronous AcceptEx failed."



=====================================================

Here is my httpd.conf file:

Admin note:
Removed the httpd.conf, see forum rules to use paste bin.


=================================================
Any possible pointers or tips will be greatly appreciated.

Thanks,

winnt_accept: Asynchronous AcceptEx failed:

be sure you have in your httpd.conf

AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off

Thanks Steffen.

It seems I don't see the error "AH00341: winnt_accept: Asynchronous AcceptEx failed" anymore but once in awhile i still see the error:

Bad Gateway

The proxy server received an invalid response from an upstream server.


Any other suggestions what might cause this error at random time?


Thanks again.

Also, if it helps --- if i refresh the page right after i get the the Bad Gateway error the page comes up just fine.
