Re: [ic] Occasional/random "Connection reset by peer" errors

From time to time, some requests to IC pages cause a page to be displayed that reads "We're sorry, the Interchange server is available due to a system error. <snip> connection reset by peer". (I'd paste the exact message, but someone here already knows the text of it -- plus, i can never seem to _make_ it show the error message.) No error appears in either the IC logs or in apache's log for that site. There were a few mentions of "interrupted system call" in the IC error log, and setting $ENV{PERL_SIGNALS} to 'unsafe' seems to have stopped that, but the "connection reset by peer" message still shows occasionally.

Where do you set PERL_SIGNALS to unsafe?

Using IC 5.3.1 (unix mode, via cgi + mod_rewrite -- not Interchange::Link), perl 5.8.8 (unthreaded), apache 2.0.53, mysql 3.23.58, and whatever perl module versions were available about 2 weeks ago.

Is Interchange in PreFork, or fork-on-demand? What is the MaxServers setting?

What operating system, distribution, kernel version?

Are you using suEXEC or a set-UID CGI binary? It sounds like you're using the compiled C-based vlink, right?

Can you see the "connection reset by peer" message in the logs? If so, is there any pattern to the URLs that it happens on?
