I was hoping to get around to it today, but I guess tomorrow will have

Thanks.

So, its ext3, dirty some pages, sync, and dirty doesn't fall to 0,
right?

Not only doesn't fall but continuously grows.

Does it happen with other filesystems as well?

Don't know. I generally only use ext3 and I'm afraid I'm not able to switch this system to other filesystem.

What are you ext3 mount options?
/dev/root / ext3 rw,data=journal 0 0
/dev/VolGrp0/usr /usr ext3 rw,nodev,data=journal 0 0
/dev/VolGrp0/var /var ext3 rw,nodev,data=journal 0 0
/dev/VolGrp0/squid_spool /var/cache/squid/cd0 ext3 rw,nosuid,nodev,noatime,data=writeback 0 0
/dev/VolGrp0/squid_spool2 /var/cache/squid/cd1 ext3 rw,nosuid,nodev,noatime,data=writeback 0 0
/dev/VolGrp0/news_spool /var/spool/news ext3 rw,nosuid,nodev,noatime,data=ordered 0 0
