Description Xixi 2009-11-07 01:21:11 UTC 
Description of problem:
Based on /etc/tomcat5/web.conf, Jasper's development mode is on by default -
"
 <!--   development         Is Jasper used in development mode? If true,   -->
 <!--                       the frequency at which JSPs are checked for    -->
 <!--                       modification may be specified via the          -->
 <!--                       modificationTestInterval parameter. [true]     -->
"
It should be off since Satellite distributes jsps pre-compiled and production satellites should no need to re-compile jsp pages.  There's a performance concern here too.

Version-Release number of selected component (if applicable):
Red Hat Network (RHN) Satellite 5.3.0 (and earlier too)

How reproducible:
Always.

Steps to Reproduce:
Look at /etc/tomcat5/web.conf

Actual results:
Jasper development mode is not explicitly turned off.

Expected results:
Jasper development mode is explicitly turned off.

on 1gb memory system with 1.5 gb swap, then upload of certificate will result in service temporarily unavailable.
satellite-sync consumes 100% cpu, but no oom in logs.
on systems with recommended amount of memory and swap not encountered any problem.
