>Description:
On a moderately  loaded server  (around 3000 requests per day on acerage,
Apache 1.3.4 (as well as 1.3.1 and 1.3.3 before it)
hits serious trouble. The server in question exports a large number of Novell shares to the Intranet via NFS; the problems appear to emerge when the Novell servers dont respond. In this case, the number of httpd processes grows, memory drains, and things grind to a halt.

Attempting to stop apache by saying
bin/apachectl stop 
produces the following warnings in error_log about children refusing to die;
httpd: [Fri Jan 22 09:39:30 1999] [warn] child process 483 still did not exit, sending a SIGTERM
... similar lines omitted --

>How-To-Repeat:
The problem appears to be specific to Solaris 2.6 and exporting novell volumes via NFS and apache.
