Annoying 502 Bad Gateway nginx ERRORS all the time

What gives? On multiples occassions at least once a day im getting this.

502 Bad Gateway
nginx

... and i cant do shit after that. Cant load the site, nothing.

Then i have to clear my cookies. Whats the problem? Getting really annoyed with this. Its not my problem its something on the server running BHW! and Firefox

It's a server error. There's a bad stick of ram that needs to be replaced, problem is finding it. Either way I agree it needs to be fixed asap.

actually its ecc memory and the box is running fine, this is related to something else and will be negated soon enough

patience please guys, ya's put a lot of load on a single little webserver
