FWIW. I see this same behavior with a similar configuration. The only differences are that I'm using oracle and am running on Sun Solaris 9.
It gets worse under heavy load. I never get complaints and have never experienced a 'browser side' problem so I assumed it didn't affect users. I get at least one of these errors an hour during the day when users are hitting the site.

Random. At least I can't seem to trigger it to happen.
/Unfortunately the logs are going to quickly for me to determine which error gave the message. The site is getting to be very busy in the run up to halloween so I wondered if it was related to the load apart from these errors the system doesn't seem to have any problems and the response is good.
What do you mean by "going too quickly"? Aren't you logging to disk? Can't you just roll the log and then inspect it at your leisure?/
I meant more trying to tie the event in real time to a message in the log. I can look at the log at leisure but it wouldn't be tied to any specific event.
/How large is the nsd process memory footprint? What modules are you loading? Did you upgrade anything at ALL lately? What OS is this on? Is it a single front-end host or a farm of them? If it's a farm, is it behind a load balancer, if so what make/model?/
OK its OACS 5.1 so apart from nsopenssl its loading tDom, nspostgres, nssha1 and nscache. We haven't changed anything in over a week. its Linux 2.4 series kernel on a single host.
/ Is your upstream bandwidth provider having routing issues? What kind of uplink exists on the host (10mbit, 100mbit, half or full duplex, configured or auto-negotiate)? What make/model switch is/are the hosts connected to? Are the switches configured or auto-negotiate? Is there any other traffic on your network segment or is it just these front-end webservers? /
Its co-lo. I've asked the host company to check the routing but so far they haven't turned up anything they'd admit too.
/ Is there a RDBMS involved, and is it running on its own dedicated host? On the same network segment? Do you serve static assets from these front-end hosts, or are you using a dedicated server for them and/or a CDN?/
Yes its running Postgresql on the same host. Not much in the way of static assets just some templating all served from the same box.
