Hi, I am able to reproduce the issue with the top-of-trunk OpenHPI ( taken from http://openhpi.svn.sourceforge.net/viewvc/openhpi/openhpi/trunk/).
I am not sure where this issue belong. It can be OpenHPI infrastructure, iLO2 plugin or hpitree utility itself (which I used to simulate). As mentioned earlier I found that, in one particular instance a thread is calling oh_get_handler (which locks the handler->lock mutex) but is not calling oh_release_handler (which unlocks this mutex). I am investigating futher to find the exact place where it is originated.

If you are able to reproduce the issue - please submit a ticket for this issue against the OpenHPI project at: https://sourceforge.net/tracker/?group_id=71730 Also, from your analysis - are you indicating this to be an OpenHPI infrastructure issue - or rather an issue with the iLO2 plugin itself?
