 Reporter:  flies  |       Type:  defect
   Status:  new    |   Priority:  normal

  Version:  3.0.3  |   Severity:  normal
 Keywords:         |
-------------------+----------------------
 Hi, we have been able to reproduce this error in version 3.0.3 (we
 previously had it on 2.1.3, 2.1.5).

 It happens very often, if the traffic is high. If the traffic is medium it
 crashes once per a day or two.

 We are using credis library in varnish VCL.

 Here's the output from screen:
