Folks,
I have a Mac client that's running 2.4.19-pre10, XFree86 (4.2.0) -query + Mozilla 1.0 and losing lots of size-2048 buffers. The rate loss is approximately 1000 buffers/hour, no reaping of the cache is ever performed, and after 8 hours or so, the system is unusable. I'm seeing this loss of memory after I boot with an initrd, get an IP address with dhclient and do a pivot_root onto the read-only NFS file system.
I can also boot the the client to a bash prompt on the local hard drive and then run XFree86 -query + Mozilla as before. Under these conditions, both with and without the local filesystem mounted RO, the size-2048 buffer utilization is nominal.
Local boot: slabinfo after 30 minutes: size-2048 5 50 2048 3 25 1
NFS Root: slabinfo after 15 & 60 minutes size-2048 187 228 2048 94 114 1 (15 min) size-2048 918 928 2048 460 464 1 (60 min)
Anyone ever seen or heard of this before? Any thoughts on how to isolate this to a root cause?
Thanks, Skip
