[SOLVED] How to fix 500 errors

[pl.zenon]

Hello,

I have ispCP Omega 1.0.0 RC6, I didn't install iscp from Daily Snapshots.
Bene, how can I use current Nightly?

pgentoo, when users receive 500 error, in log appears:

Quote:[Wed Nov 05 08:38:15 2008] [error] [client x] (4)Interrupted system call: FastCGI: comm with server "/var/www/fcgi/x/php5-fcgi-starter" aborted: select() failed, referer: x
[Wed Nov 05 08:38:15 2008] [error] [client x] FastCGI: incomplete headers (0 bytes) received from server "/var/www/fcgi/x/php5-fcgi-starter", referer: x

This error appears very usually, Some (4,5) in 1 minute.

Moreover in error.log there are a lot of:

Quote:terminated by calling exit with status '0'
[Wed Nov 05 06:22:35 2008] [warn] FastCGI: (dynamic) server "/var/www/fcgi/x/php5-fcgi-starter" (pid 9000) termination signaled

When I increase a PHP_FCGI_CHILDREN and PHP_FCGI_MAX_REQUESTS values, there are less 500 errors but after few hours site works slower than before.
