FastCGI problem

Hi,

trying to trackback to some, but not all, articles on a MovableType
installation from another MovableType installation, I get this
consistently with one entry, but not any other that I tried so far:

fastcgi request record is too big: 18446744073557966627

At the user’s side, this results in a 500 error. I have no clue where
to look, or what might cause this error, though, as trackbacks to other
entries work quite nicely.

Looking into the source of nginx suggests that maybe the 64k buffer for
the FastCGI request may be too small? But then, I don’t know if this
limit is mandated by the specs.

This is with nginx 0.7.61 on OpenBSD/amd64, pagesize = 4k. Setting

fastcgi_buffers 8 8k;

had no effect that I could see so far.

TIA!

Kind regards,

Could you please provide debug log for such a request?

Yes, 64K is FastCGI specification limit. However, the problem is in
another
place. I need a debug log.

I’m not sure that I understand you correctly.

You mean, I should build nginx with --with-debug and then say something
like

error_log filename debug_http;

Right?

Because what I sent was already that what was in the error log, and now
I even can’t reproduce the problem (aaaarrrrggghhh!).

Kind regards,

Yes, except:

  • error_log filename debug_http;
  • error_log filename debug;
