Trinidad jar - "too many open files" Exception

[Steve]

I've been getting the following exception:

java.net.SocketException: Too many open files
on a Tomcat server running on Linux. I ran lsof - p <tomcat_pid> to see 
what was going on and it seems that the trinidad jar file is being 
opened far too many times:

.....
java    3693 tomcat 1004r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat 1005r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat 1006r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat 1007r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat 1008r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat 1009r   REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar



There seem to be around a 1000 file descriptors open for the trinidad 
jar before the exception gets thrown. It's referenced much earlier in 
the list along with other jars:

...
java    3693 tomcat  mem    REG        3,5    24432 5360898 
/usr/local/tomcat/shared/lib/el-api-1.0.jar
java    3693 tomcat  mem    REG        3,5  3646899 5359580 
/usr/local/tomcat/shared/lib/trinidad-impl-1.0.2.jar
java    3693 tomcat  mem    REG        3,5  1279296 5360913 
/usr/local/tomcat/shared/lib/tomahawk-1.1.3.jar
...



Does anyone know why the trinidad jar would be opened so many times?

Thanks,

Steve
