To continue from my previous post, I've tried testing again with sun jdk 
1.6 and -agentlib:hprof=cpu=samples,depth=30 but few times after I tried 
it freezed again. It is probably related with document merging as last 
output I can get is "[IndexMerger] merged 543 documents in 7997 ms into 
_a.", then nothing happen in JBoss.

I've let JBoss starting quietly, double-checking it uses proper JVM, it 
takes 2m:35s:135ms. Then wait some times so the test server get down to 
an average load (uptime give me 0.47, 1.11, 0.85). I start testing, it 
transfer some file over the 128 total (about 4 or 5% of files I think) 
and then freezed (I last thing I get see in JBoss trace is message from 

I could try test with blackdown JVM but I think the trouble would be the 
Maybe some mutex trouble about merging ?
