Hello,

Popcon's graph generation and/or display has been broken for a couple
of weeks now.  See attached screenshot for an example, generated just
now.

Screenshot is missing, but ... I had a chat on IRC some days ago
(2026-10-08):
[18:12:17] <elbrus> it seems like
https://qa.debian.org/cgi-bin/popcon-png is broken; I get "cannot be
displayed because it contains errors"
[18:16:44] <elbrus> over on #d-devel we also chatted a bit
[18:17:13] <elbrus> XXXX found this: <pre>open2: fork failed: Resource
temporarily unavailable at /srv/qa.debian.org/cgi-bin/popcon-png line 181.
[18:17:38] <elbrus> I looked up the script, it's this line: my $pid =
open2(\*CHLD_OUT, \*CHLD_IN, 'gnuplot', '-');

It turned out it happened before and that restarting Apache sometimes
"fixes" that, as it did on 8 October.
