lighttpd dead but pid file exists

Question

Lighttpd

I periodically encounter this error on lighttpd on front-ends.
There is nothing meaningful in the logs.
Typically, this error appears during bursts of traffic.

What do you recommend for treatment?

PS don't offer the "switch to nginx" option yet. =)

PPS
Here is an example of a FastCGI config:

fastcgi.server = (
".php" =>
( "localhost" =>
(
"bin-path" => "/usr/bin/php-cgi",
"host" => " 127.0.0.1",
"port" => 1025,
"max-procs" => 500
)
)
)

It is possible that when the load reaches more than 500 users on one server, an error occurs. What are the opinions?

Answer 1

If the back-end is Apache, I suggest apt-get remove apache2.
In general, obviously, it is necessary to localize the error. Need more information.

Answer 2

what version?
after the last update of the ports, after the last port update, I started experiencing random falls of light with indistinct swearing at the proxy module. portdowngrade helped.
