I'd left a window with top running in it, and while I tried to rlogin (and after 30 seconds, I still don't have a shell prompt), I took a paste of top (see attachment). There must be something very broken somewhere here. This scenario is *not* a loaded system scenario, yet the system is practically useless. -matt [-- Attachment #2 --] 21165 root 101 0 3880K 3544K *Giant 2 2:43 10.06% 10.06% cc1 21183 root 101 0 1160K 888K *Giant 2 2:39 10.06% 10.06% sh 20212 root 101 0 2552K 2480K *Giant 3 2:47 10.01% 10.01% make 21178 root 101 0 3880K 3520K *Giant 0 2:41 10.01% 10.01% cc1 21132 root 101 0 6880K 6720K *Giant 1 2:41 10.01% 10.01% cc1 21186 root 101 0 1152K 1064K *Giant 2 2:37 10.01% 10.01% as 21184 root 101 0 1576K 1488K *Giant 3 2:32 10.01% 10.01% as 21126 root 101 0 6800K 6544K *Giant 0 2:42 9.96% 9.96% cc1 21185 root 101 0 3576K 3248K *Giant 3 2:34 9.96% 9.96% cc1 21181 root 101 0 4448K 4176K *Giant 2 2:44 9.91% 9.91% cc1 19968 root 101 0 504K 472K *Giant 0 2:44 9.91% 9.91% cc 21177 root 101 0 408K 352K *Giant 2 2:40 9.91% 9.91% cc 21179 root 101 0 1152K 1064K *Giant 2 2:43 9.86% 9.86% as 20767 root 101 0 1960K 1888K *Giant 2 2:41 9.86% 9.86% make 21173 root 101 0 1576K 1488K *Giant 0 2:40 9.86% 9.86% as 21198 root 101 0 408K 352K *Giant 3 2:35 9.81% 9.81% cc 21103 root 101 0 7928K 7704K *Giant 1 2:42 9.77% 9.77% cc1 21226 root 8 0 3176K 2024K wait 0 0:02 5.07% 3.76% login 21227 mjacob 105 0 1752K 1504K *Giant 3 0:00 3.99% 1.32% csh 21225 root 96 0 1968K 1696K select 0 0:02 1.37% 1.17% rlogin 16294 root 96 0 904K 832K select 2 0:09 0.24% 0.24% make 708 mjacob 96 0 3040K 2248K select 0 0:26 0.05% 0.05% screen 759 root 96 0 952K 880K select 0 0:19 0.05% 0.05% make 19538 root 96 0 6488K 6416K select 2 0:10 0.05% 0.05% make 17068 root 96 0 936K 864K select 2 0:09 0.05% 0.05% make 3184 mjacob 96 0 3200K 2360K CPU3 1 0:22 0.00% 0.00% top 744 root 96 0 688K 616K select 2 0:19 0.00% 0.00% make 678 root 96 0 1968K 1696K select 1 0:07 0.00% 0.00% rlogin 743 mjacob -8 0 1560K 824K piperd 1 0:07 0.00% 0.00% tee 19586 root 96 0 3896K 3824K *Giant 0 0:03 0.00% 0.00% make 396 root 96 0 4488K 2464K select 2 0:02 0.00% 0.00% sendma 390 root 97 0 4144K 2384K select 3 0:02 0.00% 0.00% sshd 230 root 96 0 1848K 1520K select 0 0:01 0.00% 0.00% ypbind 198 root 96 0 1640K 1216K select 0 0:00 0.00% 0.00% syslog 436 root 8 0 1928K 1608K nanslp 2 0:00 0.00% 0.00% cron 312 root 99 0 1728K 1448K select 1 0:00 0.00% 0.00% nfsd 680 mjacob 8 0 1880K 1776K wait 0 0:00 0.00% 0.00% bash 707 mjacob 20 0 2904K 2160K pause 1 0:00 0.00% 0.00% screen 21166 root -8 0 1576K 1488K piperd 1 0:00 0.00% 0.00% as 709 mjacob 8 0 1880K 1808K wait 2 0:00 0.00% 0.00% bash 3177 mjacob 8 0 1872K 1800K wait 0 0:00 0.00% 0.00% bash 742 root 8 0 1168K 896K wait 2 0:00 0.00% 0.00% sh 21167 root 8 0 1176K 904K wait 2 0:00 0.00% 0.00% sh 679 root 8 0 3176K 2000K wait 2 0:00 0.00% 0.00% login 19951 root 8 0 1264K 992K wait 0 0:00 0.00% 0.00% sh 399 smmsp 20 0 4360K 2336K pause 2 0:00 0.00% 0.00% sendma 219 root 96 0 2152K 1512K select 3 0:00 0.00% 0.00% rpcbin 21182 root -8 0 1576K 1488K piperd 1 0:00 0.00% 0.00% as 19960 root 8 0 1272K 1032K wait 0 0:00 0.00% 0.00% sh 21127 root -8 0 1576K 1488K piperd 0 0:00 0.00% 0.00% as 21104 root -8 0 1576K 1488K piperd 0 0:00 0.00% 0.00% as 21133 root -8 0 1576K 1488K piperd 0 0:00 0.00% 0.00% as 21171 root 8 0 1176K 904K wait 3 0:00 0.00% 0.00% sh 21197 root 8 0 1176K 904K wait 3 0:00 0.00% 0.00% sh 309 root 97 0 1912K 1520K select 2 0:00 0.00% 0.00% mountd 21170 root 8 0 408K 352K wait 3 0:00 0.00% 0.00% cc 21169 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 21100 root 8 0 408K 352K wait 0 0:00 0.00% 0.00% cc 425 root 96 0 2064K 1424K select 1 0:00 0.00% 0.00% inetd 21159 root 8 0 408K 352K wait 1 0:00 0.00% 0.00% cc 21156 root 8 0 408K 352K wait 3 0:00 0.00% 0.00% cc 21176 root 8 0 408K 352K wait 0 0:00 0.00% 0.00% cc 21175 root 8 0 408K 352K wait 0 0:00 0.00% 0.00% cc 17525 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 19535 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 21130 root 8 0 408K 352K wait 2 0:00 0.00% 0.00% cc 444 root 5 0 1736K 1424K ttyin 3 0:00 0.00% 0.00% getty 21125 root 8 0 408K 352K wait 1 0:00 0.00% 0.00% cc 19537 root 8 0 1176K 904K wait 3 0:00 0.00% 0.00% sh 21174 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 21128 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 21096 root 8 0 1176K 904K wait 1 0:00 0.00% 0.00% sh 21149 root 8 0 1176K 904K wait 3 0:00 0.00% 0.00% sh 21124 root 8 0 1176K 904K wait 3 0:00 0.00% 0.00% sh 19551 root 8 0 1176K 904K wait 1 0:00 0.00% 0.00% sh 315 root 4 0 1592K 1048K nfsd 0 0:00 0.00% 0.00% nfsd 313 root 4 0 1592K 1048K nfsd 0 0:00 0.00% 0.00% nfsd 316 root 4 0 1592K 1048K nfsd 1 0:00 0.00% 0.00% nfsd 21157 root 8 0 1176K 904K wait 1 0:00 0.00% 0.00% sh 314 root 4 0 1592K 1048K nfsd 1 0:00 0.00% 0.00% nfsd 16293 root 8 0 1176K 904K wait 2 0:00 0.00% 0.00% sh 16299 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh 758 root 8 0 1176K 904K wait 0 0:00 0.00% 0.00% sh
