JVM crash in [libnet.so+0x9243] Java_java_net_SocketInputStream_socketRead0+0xb3

[Ronald Klop]

First upgrade Tomcat. Your version is from Jan 2010 [1] or earlier. There  
are a lot of bugfixes in Tomcat about NIO since then. And also for  
security reasons [2].
Tomcat 6.0.35 is also in ports.
Second, can you reproduce this with openjdk 6?

Do you write hundreds of files per second or per day?

Ronald.
