*CUSTOMER REP:  James Robertson, Jerry Rico

 PROBLEM:       The console is responding slowly.
                P70 monitor

*ACTION TAKEN:  \#errpt -a | more --> 
                        LABEL: SRC

                        Date: Sat, Oct 11
                        Failing Module: fibred
                   Because of the date I don't believe this to 
                        be the cause.
                Running Commondesk top environment.
                \#lsps -a --> one paging lv with 64 MB on hdisk4 at 60%
                Faxing paging.space.tips.lxp to 912-471-5099
                Suggested increasing Paging Space
                
                lsattr -El sys0 --> maxmbuf 0
                no -a --> thewall = 16384

                We increased the ps by 2 LV on other disks.
                        Now the lsps -a is down to 1%.

Adding The following Text, not added when the LIBRARY item was created:

*CUSTOMER REP: Jerry
 PROBLEM:  -- need help to configure the en2 en0  even if they sre slow
          -- since cust needs the printserver to activate
*ACTION TAKEN:
            netstat -rn has all the double lines -- for lo0
            en2 has four lines --
   lssrc -a !pg
   inetd portmap routd timed xntpd dpid2 muxatmd are active stopsrc -g
tcpip startsrc -s inetd
    flushued the routing --
  ifconfig en0 down and detach -- same thing on en2 and lo0
  rmdev -l en0 as well as en2 lo0
  rmdev -l en0 -d sa well as en2 lo0 inet0
  rmdev -l ent0 ent1 ent2
  cfgmgr -v
  -- then configure the en2 and en1
  tn en2 interface was slow --- but it does not matter at this point
-- any way I checked  the netstat -m:
 45 mbufs in use:
 0 mbuf cluster pages in use \<-----
                            - this explained to me i.e some thing
wrong
                            -  with network parameters --
 11 Kbytes allocated to mbufs
 0 requests for mbufs denied
 0 calls to protocol drain routines
checked the /etc/rc.net had the following set:
           \# /usr/sbin/no -o tcp_sendspace=16384
           \# /usr/sbin/no -o tcp_recvspace=16384
          /usr/sbin/no -o tcp_sendspace=1180
          /usr/sbin/no -o tcp_recvspace=1140
   had the cust to change them back to default:
           /usr/sbin/no -o tcp_sendspace=16384
           /usr/sbin/no -o tcp_recvspace=16384
suggested shutdown -Fr --- ---!!!!!!! Guess what !!!!!!!!!!--- now the
problem has been resolved -
   telnet works fine as normal as default system ---
 cust asked me how those values got changed --- Some one must have
  changed who has the root access on the system ---
*ACTION PLAN: any other questions? no
          cust is very much happy now and thanked every one who are
           all involved in this issue :
