Hi all,
My java application (running in "Java HotSpot(TM) Server VM (build
14.0-b16, mixed mode)" on Sun Netra T5440) using Xalan transforms
thousands of XML files (uses 16 Threads). After it transforms about 5000
XML files, it becomes slow and it starts transforming very slowly and it
takes 2mins for some transformation (where the first transformation of
similar XML with same XSLT ran in just 2 secs). One of the Thread Dump
is as follows

I couldn't find any bug other than 2336 and 2344 that talks about
Vector. Please share any info, by which I can achieve consistent
performance.
Thanks in advance,
With regards,
R Kaja Mohideen
