Summary

0000180: High memory usage in reconstruction

Description

I'm running into a problem with this hddm file:
http://www-meg.phys.cmu.edu/~wilevine/memory_issue/memory_issue.hddm [^]

When I run:

hd_ana memory_issue.hddm -PPLUGINS=danahddm

memory usage stays relatively flat for a while then suddenly jumps to
several GB, at which point the program stops analyzing events and must
be killed.

davidl was able to reproduce the problem and has found a minimal range of events that trigger the problem.

The issue is reproducible in svn revision 6810, but absent in rev 8643, at least for the file linked above, but there is some skepticism that the underlying issue is resolved.
