SUMMARY: Syslog message 'You've run out of swap file numbers.'

I received two replies regarding my question:

Casper Dik <casper@holland.sun.com> explained that messages are logged
with the string 'syslog:' if the application doesn't do an openlog-call.

Charles Holbrook <ctech@bmic.net> suggested checking that enough swapspace
is available and that the number of files in /tmp is not to large. I checked
both of these before posting, lots of swap is available and very few files
in /tmp.

Since the message isn't logged by the kernel itself, I started looking at
the applications running on the machine: Our squid-proxy is one of the
large applications on that server. I greped through the sources and voila:
squid is the one logging these messages. We are currently checking different
squid-resources to get a clue what goes wrong. Things would have been
easier if squid had logged the messages with 'squid: '...

Original question:

Since yesterday, one of our Ultras running 2.5.1 has the following
message in the messages file:
 
Oct 15 10:17:27 hostname syslog: You've run out of swap file numbers.
 
The message repeats every couple of hours.
 
Does anyone know what causes this message? Note that is logged with
facility syslog. I did a 'strings syslogd', but the syslogd-binary
does not contain this string. What else could log this message
with facility syslog? There is plenty of swapspace available.
