[users@httpd] strange behaviour during httpd start: chown operation 1 pro second
Hello,
I'm using apache server 1.3.41 on a solaris 10 system (x86). in httpd.conf
I set:
...
MinSpareServers 10
MaxSpareServers 90
StartServers 90
MaxClients 90
...
When starting apache via 'apachectl start' I see that these 90 processes
were started quite immediately, but it took almost 1,5 minuts before each
of the child processes changed their owner from root to another local
user.
it is also suspicous, that when studying the ps output, that between each
change of owner for a further child process, a period of 1 second seemed
always be used.
In the documentation I find no hints for this behaviour. Only the
behaviour of minspareserver and maxspareservers give hints, that there is
a method implemented to spawn a certain amount of child processes per
second.
However, does someone know what is causing this observed behaviour?
The problem here is, that no request is served before not all child
processes changed the ownership.
Thank you in advance!
Harald

Hello,
yes, I'm using NIS. - How can I find out, if NIS is really the problem? I
studied the system calls via truss, but could not determine that NIS is a
problem here. Maybe I have overseen something.
How did you worked around this problem?
regards
Harald

Are you using NIS or LDAP on your system? The only hang in this
neighborhood I've ever seen was when LDAP was used for groups and
getgroups() would take seconds.
