iCMS question

Hi all,

I'm looking at an i-cms log, and I don't understand why I'm seeing what I'm
seeing.  Any help is appreciated.  At about 38718.035 in the log below,
icms_dc begins to report 100, and just after that I see several back-to-back
concurrent mode failures.  During that time, the ParNew collections are
reporting that they're doing no work.  This happens on and off for about 20
minutes in the log.  Obviously the collections are taking seconds, but I
don't see a Full GC every time.  What is it doing when it's not doing a full
GC?  Is the continual CMS collection preventing the young generation from
being collected (or perhaps collecting it simultaneously)?  When
icms_dc=100, does that imply the application is stopped?

There was some uninformed command line twiddling going on here, so the GC
parameters were:
-Xmx1152m
-Xms256m
-XX:NewRatio=4
-XX:MaxPermSize=128m
-XX:+UseParNewGC
-XX:-CMSParallelRemarkEnabled
-XX:+UseConcMarkSweepGC
-XX:+CMSPermGenSweepingEnabled
-XX:+UseCMSCompactAtFullCollection
-XX:CMSFullGCsBeforeCompaction=1
-XX:+CMSClassUnloadingEnabled
-XX:+CMSIncrementalMode
-XX:+CMSIncrementalPacing
-XX:CMSInitiatingOccupancyFraction=50
-XX:ParallelGCThreads=1
-XX:MaxTenuringThreshold=0
-XX:SurvivorRatio=1024
-XX:SoftRefLRUPolicyMSPerMB=1000
-XX:+DisableExplicitGC
-XX:+PrintGCDetails
-XX:+PrintGCTimeStamps
-XX:+PrintGCDateStamps

I had them remove -XX:ParallelGCThreads=1, -XX:MaxTenuringThreshold=0,
and -XX:SurvivorRatio=1024 , thinking that since the duty cycle was
approaching 100%, and because the ParNew pause times were so low, we could
probably afford to spend more time doing young gc's instead of promoting.
 I'm thinking I should probably tell them to increase their -Xmx and
decrease their NewRatio as well.  Is there anything else?  I haven't done
much tuning of i-cms in general, but the standard i-cms safety options don't
seem like they would help here.

Here's the log excerpt:
