Hi All ,
        Couple of things . swapon -s shows :

Swap partition /dev/re0b (default swap):
    Allocated space: 447159 pages (3493MB)
    In-use space: 1 pages ( 0%)
    Free space: 447158 pages ( 99%)


Total swap allocation:
    Allocated space: 447159 pages (3493MB)
    Reserved space: 382255 pages ( 85%)
    In-use space: 1 pages ( 0%)
    Available space: 64904 pages ( 14%)

 
        The reserved space is 85 % .
        Any idea why it would be so high .
        I always have 300+MB of memory to spare .
        I have a few identical systems , the others
        use no more than 35 % .
        These systems are used to run a 2 engine sybase
        dataserver . Also as shown with top , only on this machine
        the dataserver is started up with a static 900
        MB and only grabs 1.6 MB ??
        The 2 engines do not grab 900 each , it just looks like
        it .


  PID USERNAME PRI NICE SIZE RES STATE TIME CPU COMMAND
15428 sybase 53 0 909M 1744K run 146.2H 98.70% dataserver
