[sword-devel] CrossWire Server Problems

There have been some problems with the server lately.

I think, but am not sure, that tomcat is having problems. I'm not very  
up on tomcat, so take what follows with a grain of salt.

For those with server access and appropriate permissions, tomcat logs  
have a wealth of info and can be found at:

In catalina.out the following error is repeated frequently:
java.io.FileNotFoundException: /opt/tomcat/webapps/gobible/WEB-INF/ 
classes/trans_null.properties (Permission denied)
This is followed by a java stack trace.

The only other errors I see in that file are related to the Bible  
Tool, where the process tries to attach to a running process (throwing  
an exception) and then starts another process because of the failure.

Other than that this log indicates a heavy usage of the forums.

In catalina2009-04-16.log
There are a lot of problems opening jar files. Doing a spot check  
indicates that the jars are fine. But looking a bit closer in the log,  
each one of these is followed by a stack trace indicating "Too many  
files open"

Musing out loud: It appears that some of the more common jar files are  
repeated for each webapp. Should they be put in a common area? (I  
don't know enough to know.)

I'm also wondering whether the BibleTool holds too many open file  
descriptors? (I have no idea, but JSword had that problem.)

The number of open file descriptors is a tunable kernel parameter, so  
maybe it can be adjusted upward?

Anyway, this is probably more heat than light.

In Him,
