We recently introduced some code on our site which appears to be
causing SocketExceptions that eventually bring JRun to its knees. The
site is running JRun 3.02a.47579 on Solaris 8, and with the exception
of this new code, has run like a champ for over a year.
The new code is using the following line in a bean to retrieve 2-3
small jsp files from the filesystem and plug them into a parent jsp
file:
pageContext.include(m.getFileName());
I've included the stack trace below. This line is what occurs at
SlabTag.java:44.
The working theory is that these reads to the file system are
overloading system resources. I'm wondering if someone can tell me if
JRun caches the information obtained from pageContext.include() or if
it is indeed reading from the file system each time this line is run.
If this is a plausible theory, can someone give me some pointers for
revising this line to something similar which does caching? If the
theory is not even in the ballpark, what else might cause this error?
thanks, Kari
