We are using ListServ 1.8e in Solaris Sparc 7 (ES250 machines with 2 
CPUs).  We had a problem in a list index which always crashed the 
ListServ.  The archive (*.logXXXXX) have 256 weekly archives (there are 
more than one archive in a single week) and the total size is 448Meg. 
The ListServ would crashed if any user did a search on that list.  I 
deleted the *.db* corresponding to that list and could see it rebuilt the 
index when I did a search.  But ListServ crashed 5-10 mintes later that I 
had to re-start it.  The last few lines of log I saw before the crash 
were:

*** FIO file cache now totals 20862k. A list of cached files follows. ***

I noticed that there were a lot of 'U' under the 'Flags'.  I would be 
appreciated if any one could let me know what is going wrong or I missed 
something.  I searched the LSTSRV-L and could not find anything.  Thank.
