Had another hotspot crash on a Linux server again today after months of not having any. Doing a bit of googling and finding myself back on Steven Erat’s very useful blog I found a user comment saying that in Sun’s JRE 1.4.2_10 they seem to have fixed the problem. As a result I’ve updated it along with a couple of hotfixes to CF and all seems well. You can get the JRE from Sun’s Java site.
