Scott, I finally just moved my webapps to my Open Solaris machine, which is much more modern, and has a lot more RAM available. (It is currently running resin-4.0.0, warts and all.) This will allow me to update the older machine at my leisure. The problem I'm facing now is twofold, and the first of these might be related. 1) Attempts to upgrade to resin-4.0.5 have failed. Resin seems to run fine, but then stops after an hour or two. Because this machine is more critical (it hosts the data for my iPhone app), I just switch back to resin-4.0.0, which has problems but is stable. More details about how I installed it below. 2) On both 4.0.0 and 4.0.5, I have problems with Quercus and WordPress. In 4.0.0, I get a StackOverflowError. In 4.0.5, I get a PHP report of a database connection error (and I believe that comes with a 500 response). Installation Details -------------------- The configuration for both is exactly the same, as much as I can remember and glean from my history. I put the individual resin released in /usr/local/resin/versions(/resin-4.0.0, resin-4.0.5, etc.), and symlink one of those to /usr/local/resin/current. When I installed 4.0.0, I believe I set that up first, then ran ./configure --prefix=/usr/local/resin/current, then make, sudo make install. For 4.0.5, I put it in place, but left the symlink pointing to 4.0.0, and did configure --prefix=/usr/local/resin/versions/resin-4.0.5, make, make install (not sudo). This complains that it couldn't install /etc/resin/ stuff, but I already had that from the previous build. Now, when I switch between versions, I change the symlink, and blow away all the WEB-INF/work directories (I'm posting a separate question about that), sometimes I stop and restart the server via the resin.sh script I have (which is just a wrapper around: java -jar /usr/local/resin/current/lib/resin.jar -verbose -root-directory /var/www -conf /etc/resin/resin.xml $* But usually it restarts itself (because of the symlink change, I presume). When I get some time, I'll try with resin-4.0.4, but I'm supposed to be doing "real" work for my employer today. -- Rick _______________________________________________ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
