InterruptedIOException when loading pre-compiled JSP

[Eric Dalquist]

I'm using Tomcat 6.0.20 on Solaris 10 and JDK 1.6.0_16

I have a webapp that seemingly randomly fails to work due do a
NoClassDefFoundError. The .tag files and JSPs are being pre-compiled and
the webapp's web.xml is modified to reference the pre-compiled classes.
My application code fails with the error:

Caused by: java.lang.NoClassDefFoundError:

What I see in catalina.out the first time the webapp fails is the
following InterruptedIOException. It appears that the classloader
reading from the file is interrupted somehow which causes the class load
to fail and once it has failed once it is never retried. My only
resolution is to restart the server. I haven't been able to pin down any
particular cause for this problem yet. Has anyone here seen anything
similar?

If you are seeing InterruptedIOExceptions along with this, could it
possibly be the most obvious cause: your hard disk has errors?

That was our initial reaction as well but the syslog doesn't show any hard disk errors but we may end up looking into more detailed diagnostics of the disks.

Finally had OS maintenance to do and a fsck found some errors in the superblock. We haven't seen errors since the fsck so as suspected file system errors were the underlying cause.
