This sounds like it may be a kernel tuning issue. A quick google on
errno:46 shows that it looks like the box is running out of file locks
(controlled by kernel parameter nflocks). If you have a bunch of processes
running on this box, and your box has not been tuned and is using the
default kernel values, this may not be enough.

HP provides more information, and HPjconfig, a kernel tuning tool, over on
their Java site:

What else is running on this machine when you are running Tomcat/BIRT?

there is nothing else running. I had posted the same qusestion on BIRT BUG
List.
It looks like an issue with the report engine.
This is what they said.

"Engine adds lock manager when reading and writing
document.(DocArchiveLockManager)"

"We can remove the file lock to solve this issue. It would be in a 2.1.2
daily
build however."
