DODSLockMaster Timeout expired

Hello,

I developped some taglib to get informations about assignements of current web user.
While stressing the taglib to get a bit of informations on how much simultaneous users the
web interface, i randomly got some of those exception, the more simultaneous threads, the more
exception. 

org.enhydra.shark.api.RootException: Timeout expired waiting on 3_test_bs_domath

I worked around the problem when testing with hsqldb by setting this in shark.conf:
DODSLockMaster.Timeout=3000
DODSLockMaster.LockWaitTime=40

However this doesn't seem to have an effect when using the oracle database. Is there any suggested solution?
Thanks
