FIOC_WARNING

This configuration variable defines the cache size (in kB) at which LISTSERV should write a warning to the console log. See the LISTSERV Tuning Guide (available from L-Soft at no extra charge) for more information.

This is one of three variables that controls how LISTSERV handles its cache. Under certain circumstances, LISTSERV may not be able to trim the cache right away, either because a cache entry is locked by a routine that maintains pointers to it or because the file is currently open and thus it would be counter-productive to flush the cache entry right away. In such cases, the cache size can continue to grow past FIOC_TRIM. When it reaches FIOC_WARNING, a warning is displayed in the LISTSERV log. This probably indicates a programming error, or a value of FIOC_TARGET that is significantly below the "correct" value for your workload. Typically this value should be set to FIOC_TARGET plus 75% or 1MB (whichever is larger).
