I've made a simple patch for the issue which solves it on my machine:

in timer.erl:

231,237c231
<                     NewTime = case (SysTime - Time) of
<                     I when I > (Interv * 4)->
<                       %% RvG Don't try to catch up on events
<                       SysTime - (Interv * 2);
<                     I ->
<                       Time + Interv
<                   end,
---
 >                   NewTime = Time + Interv,

In this case, we only catch up if we are less than 4 intervals behind
