the first one should be fixed with the new release. With old
versions, ctl module doesn't inherits the user/group set by the
core, you would have to set it in the ctl module via params.<br>
<br>
The second can happen in very rare cases -- if there was a
transaction in the process of freeing, then signal interrupted it.
Parts of the transaction structure that were freed could have been
allocated already and value overwritten. But the transaction itself
was not removed from the list, so the main process will attempt a
cleanup at shutdown, ending in some invalid pointer data.<br>
<br>
If you get it every time, then is likely a bug. If you get it very
rare, then it can be the above case.<br>
<br>
Perhaps we can add a flag saying it is shutdown where to be more
flexible in handling these situations.<br>
<br>
