dear developers,
i'm running a jackrabbit system with several workspaces (15) and using derby as
embedded database on suse linux.
since a few days and after adding another workspace i get exceptions like the
one that i've attached to this e-mail (reproducable with jackrabbit 2.2.9 and
2.2.10). i'm suspecting that the failure is originated by the number of
workspaces.
ulimit -n prints out a value of 1024.
do you have recommendations how to deal with this issue?
best regards, ulf.
