#188: thread pileup
 Reporter:  steinove  |       Owner:  des  
     Type:  defect    |      Status:  new  
 Priority:  high      |   Milestone:       
Component:  build     |     Version:  1.1.1
 Severity:  normal    |    Keywords:       
 On centos 4.4, 2.6.9 smp kernel, varnish 1.1.1

 When number of requests gets high enough (5000-6000 req/s), suddenly
 threads starts piling up to the max, cpu goes to 100%, server load goes to
 1000 in a few secs.
 This results in a huge number of overflowed work requests and dropped work

 DES has more logs of the problem.
