Directory quotas changed in NetWare 6.5 SP1 to allow only two directory quota threads to run simultaneously. Other initialization requests for directory quotas are queued to run on one of the two threads. You will not notice any difference because the functions return with a success return value as soon as the request is queued. It might take a while for the background threads to return the current amount in use value the first time a quota is set. However, this functionality keeps the system from going into high utilization.
This directory quota behavior change occurs whether you are using the 64-bit File System APIs, NLM and NetWare Libraries for C (CLib), or Libraries for C (LibC).
Also, any allocated search maps must be closed when they are no longer in use to avoid problems with reusing search maps.
