Re: [Resin-interest] Resin keeps restarting...
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Peter, I have a server that Resin keeps restarting every 15-20 minutes. Where should we start to look to see what is going on. I just enabled full debug logging so starting to gather that information. I'd like to know any pointers we should start looking at once some data is captured. maybe your jvm memory is running low and so the watchdog process restarts your env. It might help to just increase your jvm mem a bit by adding jvm-arg-Xmx1536m/jvm-arg to your resin config. (You didn't write which version you're using, so I assume v4.x here) Best regards, --- Jan. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (Darwin) iEYEARECAAYFAkujJQwACgkQME/SSH3iSFlOtQCeKyhdsKsadgI6Rg0QpY5JvTRA Z1wAnj3q09Lx41IIAJHxGbREwLFZH92B =dAnl -END PGP SIGNATURE- ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] Qeurcus Stack Overflow (resin 4.0.0)
Hi. Under resin 4.0.0, my Word Press installation fails with a stack overflow.
The bit of PHP triggering it is the line with do {:
reset( $wp_filter[ $tag ] );
do {
foreach ( (array) current($wp_filter[$tag]) as $the_ )
if ( !is_null($the_['function']) )
call_user_func_array($the_['function'],
array_slice($args, 0, (int) $the_['accepted_args']));
The stack trace excerpt is (this is the lastmost portion in the log; it
continues prior to this for a long time):

It appears to be stuck in an infinite recursion. Any ideas? I see there are two
stack overflow-related fixes in 4.0.0 and 4.0.1, but if this isn't the one
fixed in 4.0.1, I don't want to try to upgrade Resin (I tried to upgrade to
4.0.5 today, and it failed to work well).

Re: [Resin-interest] Classpath Question
I think what you want to do is add class-loader library-loader path=/opt/server/java/ /class-loader To your resin.xml. At least, that's how I do it in resin-4.0.x In 4, you can also add all those Java args in the resin.xml file (I think you can in 3.1, too, but I don't know for sure).

My stress testing isn't showing anything like this kind of behavior yet, but any further details would help narrow the tests. 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

The configure script uses java -version to see if it's 64-bit and as you showed below, java -version is 32-bit on your machine. (And Resin's configure script won't try to assume that you really want to use -d64.) Even with --enable-64bit, it didn't find that java was 64-bit. Does --enable-64bit override that? Even so, it ran into other problems as a 64-bit build.
