Hi managers,

   Our configuration is an ES40 with 1.5G of RAM V4.0F patch 3.

   This afternoon a programmer was telling me that he received an error
message from the system.

   He was looking at some logs file in the system. To look at them (60
files), he simply issue a vi fil*log. The
size of files was small (each approx. 100K). After viewing the 63rd, the
system display the message "not
enough memory available". Here are two ouput from vmstat:

   # vmstat -s;sleep 300;vmstat -s
