What is cupsd doing at this stages?

[Anonymous]

Thanks for the suggestion. However, even after making the changes,
it's still doing the same thing. That is, the cupsd continues to use
cpu even when all printers have already been received.

root at sapti01f:./cups1123 # ps -ef|grep -i cups
    root 1732630       1 107 10:33:55      - 29:53 /opt/TWWfsw/cups1123/sbin/cup
sd -c /etc/opt/TWWfsw/cups1123/cupsd.conf
root at sapti01f:./cups1123 # ps -ef|grep -i cups
    root 1732630       1 102 10:33:55      - 29:54 /opt/TWWfsw/cups1123/sbin/cup
sd -c /etc/opt/TWWfsw/cups1123/cupsd.conf
root at sapti01f:./cups1123 # ps -ef|grep -i cups
    root 1732630       1  88 10:33:55      - 29:55 /opt/TWWfsw/cups1123/sbin/cup
sd -c /etc/opt/TWWfsw/cups1123/cupsd.conf

And it get stuck in the same place:
stopped in strcasecmp.strcasecmp [/usr/lib/libc.a] at 0xd01f961c ($t1)
0xd01f961c (strcasecmp+0x1c) 7ce638ae       lbzx   r7,r6,r7
(dbx) where
strcasecmp.strcasecmp(??, ??) at 0xd01f961c

ProcessBrowseData() at 0x10028bf4
UpdateCUPSBrowse() at 0x10027848
main() at 0x10000e28

However, I think the issue is not with CUPS anymore. I installed CUPS
1.1.23 on a simillar system running the same OS, hardware, etc, and
copied over the cups configurations and it worked just fine.

root at sapti02:./cups1123 # lpstat -a|wc

root at sapti02:./cups1123 # ps -ef|grep -i cups
    root 454896      1   0   Apr 12      -  0:01 /opt/TWWfsw/cups1123/sbin/cupsd
 -c /etc/opt/TWWfsw/cups1123/cupsd.conf

stopped in select at 0xd0268bdc ($t1)

(dbx) where
select(??, ??, ??, ??, ??) at 0xd0268bdc

Is there a future plan of implementing a database to be used with CUPS?

Finally, I've also posted a message couple of days ago about load-
balance and fail-safe operation with BrowseAddress on servers only. Is
that possible? I've tested it and the client was able to print to the
primary server(using ServerName) but when the primary server is down,
it's not able to print to the secondary server. As if the secondary
server doesn't exist.
