Here's an example of the load being driven up, when only one printer has a queue, note that the delay betweeb jobs is proportional to the length of the queue. The load here is 2.50, this top output is displaying all processes for the 'lp' user, the processes are: 5639 - the 'main' lpd process 6121 - the 'server' process for this queue 7214 - the process for the job that has just printed 2:05pm up 25 min, 2 users, load average: 2.50, 2.02, 1.27 68 processes: 64 sleeping, 3 running, 1 zombie, 0 stopped CPU states: 94.4% user, 5.5% system, 0.0% nice, 0.0% idle Mem: 513192K av, 245952K used, 267240K free, 0K shrd, 5928K buff Swap: 530136K av, 0K used, 530136K free 186672K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 6121 lp 25 0 6776 6776 2108 R 50.1 1.3 4:43 lpd 5639 lp 15 0 1792 1792 1600 S 0.0 0.3 0:00 lpd 7214 lp 16 0 0 0 0 Z 0.0 0.0 0:00 lpd <defunct> And here is the actual queue at the time of the above top output (with usernames and hostnames changed). Is having this number of jobs in the queue enough to cause the load to be this high, or is this symptomatic of some problem? This machine only does print serving.
