  Sorry, not much help.
  Can you explain me, why qrunners take more and more memory (RES)?
  It was 25Mb maximum in my previous letter, now it is 36Mb:

$ top
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                                  
17660 mailman   15   0  101M  36M 2668 S  0.0  1.8   0:41.33 qrunner                                   
32356 mailman   15   0  100M  35M 2668 S  0.0  1.7   0:38.30 qrunner                                   
17584 mailman   15   0  100M  35M 2668 S  0.0  1.7   0:40.04 qrunner                                   
32739 mailman   18   0 99.7M  34M 2660 S  0.0  1.7   0:33.94 qrunner                                   
 3182 mailman   15   0 99.5M  34M 2668 S  0.0  1.7   0:39.10 qrunner                                   
...

  Some of them took up to 200Mb (!) before I had to restart them.
  All this looks like slow and fast memory leak.

  My vmstat, if you are interested in:

$ vmstat -a 1 3
procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu----
 r  b   swpd   free  inact active   si   so    bi    bo   in    cs us sy id wa

 0  0      0 1302408      0      0    0    0     0     0    0  1625  0  0 99  1
