Steve, We had a problem where periodically we would show up in the morning to find that our bathy_catalog.xml would only have 1 entry instead of the 30 or so that it should have. And restarting tomcat fixed the problem. Eventually we discovered that by blocking web crawlers our problem went away, and the reason speculated by our sys admin was that the crawlers were gobbling up all the tomcat memory. So yes, we've seen problems where only one THREDDS catalog seems to be affected, perhaps by memory issues, and restarting Tomcat helps. Perhaps your attempt to aggregate 3 years of forecast data into the FMRC aggregation is blowing things out? I think we need a tutorial (webinar?) on caching, aggregation and memory... -Rich On Thu, May 28, 2009 at 9:49 AM, Steve Cousins <address@hidden> wrote: > Hi Rich, > > Do you have problems with THREDDS data sets going away?
