symptom
Server is getting Low Priority Thread error messages.
Message: "SERVER-4.11-1616 An NLM has been loaded that does not allow low priority threads to be run. Low priority threads are used for file compression, etc. Set 'Upgrade Low Priority Threads' to ON or unload the NLM."
cause
An NLM on the server is complaining that it is not getting enough CPU time. Setting upgrade low priority threads=on will give all NLM's HIGH priority and cause high utilization on the server. This error is usually caused by some NLM or process running that is taking a high CPU percentage.
fix
You need to determine what NLM is loaded or Process running that is monopolizing the CPU. One likely cause is lack of free blocks on the volumes. It is important to keep more than 1000 "free blocks" and at least 10% to 20% free disk space on each volume with suballocation enabled. Suballocation uses these free blocks to free up additional disk space. The number of free blocks can be viewed in Servman.nlm under volume information. There are two values to check for under each volume (free blocks and freeable limbo blocks). Free blocks are purged blocks. Freeable limbo blocks are the number of blocks that could be free'ed if a purge were performed.
