Out of memory exceptions with V1.0 release 9

Support

Hi folks - left Roon running overnight and this morning the server had crashed - it seems to have run out of memory. Nothing much else was running on this Mac - I had even closed iTunes. Excerpt from log file as follows:

Please take a look and let me know if you need the full log file. There are a lot of exceptions after this one - thanks

Hey @pcwilliams – @vova and I will be in touch to get some logs here. Tough week :frowning:

This is almost certainly caused by a giant logfile associated with a managed crash. I see badness in our code where the entire logfile is loaded into memory. I’m looking to fix this.

In the meantime, if you blow away log files ($HOME/Library/Roon/Logs) and serialized crashes ($HOME/Library/Roon/Database/Cx) this will stop (at least until you crash again with big log files…).
