This leads me to believe that upstream is aware of this issue and someone there is working on a fix.
I was reading your posts with Joerg Schillings comments on Linux NFS (in the zfs/xfs/jfs thread) still in the back of my head, for some reason ;)
The changelog entries in upstream's autofs rpm go back thirteen years. One would expect some measure of maturity and stability here, yet autofs is a frequent source of problems. I remember another major problem we ran into somewhere around CentOS 5.2 or 5.3.
I do see maturity and a great many improvement but I must agree that comparing the change log to bug reports seems to indicate a level of instability. There do seem to be a great many bugs that dump core but this may be the nature of the beast when interacting with the Linux kernel, a constantly moving target. I'm not one to criticize but if software in our organization repeatedly produced segfaults, I'd suggest that developers look closely at improving error traps and handling and/or analyze faults to see if patterns or trends emerge. Still, there are enough alternatives and security features in EL to mitigate most problems.
