System Administration Guide: Naming and Directory Services (FNS and NIS+)

Logs Grow too Large

Failure to regularly checkpoint your system with nisping -C causes your log files to grow too large. Logs are not cleared on a master until all replicas for that master are updated. If a replica is down or otherwise out of service or unreachable, the master's logs for that replica cannot be cleared. Thus, if a replica is going to be down or out of service for a period of time, you should remove it as a replica from the master as described in Removing a Directory. Keep in mind that you must first remove the directory's org_dir and groups_dir subdirectories before you remove the directory itself.
