- We had a similiar problem which appears to have been a kernal
- memory leak in the asy driver. This is in Dell's issue 2.1
- which is system V R4.
-
- Use "sar -k" to see your kernal memory statistics.
- If you don't have sar running, now is a good time to add it:
- At startup in inittab or via an init script:
- su sys -c "/usr/lib/sa/sadc /var/adm/sa/sa`date +%d`"
- In the sys crontab:
- 0 * * * * /usr/lib/sa/sa1 240 15 # every 4 min
-
- All of our problems went away when we replaced the asy driver with
- SAS. (Actually we use both, but the asy driver almost never sees
- activity on the DOS port it handles.)
