>Description:
Enabling the Cache function of apache 1.2b10 seems to work (and work well)
for a short period of time, then after several users hit the system (via
the proxy) the error_log file grows at an alarming rate with the following
error messages

[Wed May 14 16:16:23 1997] open:
/export/home/httpd/proxy///////////////////////
////////////////////////////////ime: Too many open files
[Wed May 14 16:16:23 1997] open:
/export/home/httpd/proxy///////////////////////
////////////////////////////////ime: Too many open files

////////////////////////////////ime: Too many open files

The proxy directory access is available to HTTPD and it writes a
multitude of directories and files. Definitely functioning as
cache, already tested via browsers.
>How-To-Repeat:
Setup with standard configuration:
Stock Standard Configuration (at least until it works)

ProxyRequests On
CacheRoot /export/home/httpd/proxy
CacheSize 5
CacheGcInterval 4
CacheMaxExpire 24
CacheLastModifiedFactor 0.1
CacheDefaultExpire 1
NoCache no1.co.nz

Will work well at first, I had 4 users proxied to the server, after 
approx 30 mins use the log file grows out of control with above messages

Same problems with Virtual host (same ip) through port 8080
