Deadlock on compliance computing

Web - Compliance & node report
Description
I generated policies, accepted nodes and the same time, and went to home page several time
after a while, compliance didn't show up...
running jstack show that a lot of thread are BLOCKED (see attachement)
Files
I had a query 'idle in transaction' in postgresql: select nodeid, nodeconfigid, begindate, configuration from nodeconfigurations where enddate is null;
this was because of the load script
There is also an issue on the policy generation: calling policy/regenerate every 30 minutes causes it to lock after first generation after midnight: every subsequent call results in
<title>502 Proxy Error</title>
