From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)

Description of problem:
when the number of nfs mounts gets too large(usually 256) we get this 
message: "mount table full".
Is there a way to increase the number of nfs mounts?


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.easy to reproduce just by doing a whole bunch of mounts from remote machines


Steps to Reproduce:
1. use a loop to do lots of mounts from another server
2. check after each mount how many mounts
3. eventually get  "mount table full".

	

Actual Results:  "mount table full", won't do any futher mounts, and we think 
automount gets confused and won't unmount when quiet.

Expected Results:  automount should have nfs mounted other users' home 
directories
from other machines, but it can't until some of the currents mounts are 
unmounted.

Additional info:

we think that this might be a configarable limit that can be set in /proc, but 
where?

There was a post recently on the linux-nfs and linux-kernel mail lists  - see:

Which I _think_ relates to your problem ...

I believe we do a better job in later kernels. Please
try the Fedora Core kernels and reopen if necessary
