automount eats up 100% of CPU

From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2smp i686) I have a dual processor Pentium III. Since upgrading to RedHat 7.1, automount will eventually go into a mode where it eats of 100% of one of the two CPU's as indicated by top and xload. Despite this, it automounting still works. Reproducible: Always Steps to Reproduce: 1. Find a dual processor Pentium System. 2. Set /etc/auto.master to: /nfs /etc/auto.nfs 3. Set /etc/auto.nfs to: * -fstype=autofs,-Dhost=&,-Dprefix=/& file:/etc/auto.nfs.sub 4. Set /etc/auto.nfs.sub to: * ${host}:${prefix}/& 5. # service autofs start 6. Wait a few days. Actual Results: automount consumes 100% of one of the two CPU's. Expected Results: automount should have consumed only a very small fraction of the CPU's.
Can you give strace output for the offending process?
The problem went away, as far as I am aware with Red Hat 8 or 9, so (1) I no longer have a machine that exhibits the problem, and (2) it probably is moot now.
