I don't know any bugtracker or something so I just post my report here so it doesn't get lost. I had the nxt server running for a few hours, then I put the machine in standby and traveled home. I took the machine up again in another WLAN and the Wallet-Page stopped responding. I found Java was running out of heap-space:

I'm here for questions and tests. I'd also provide the logs if they help. Feel free to ignore this post if it is a known issue.
