runConcurrentThread function failed

I use Cynical SecuritySpy to put a camera in to active mode when the alarm is set and passive on unset. Recently it has been logging errors, though seems to still be setting the camera active/passive correctly.

Am using b10 and plugin 1.4.1.

The alarm unset trigger (turning camera passive) logs very similar events.

Any suggestions? Thanks.

Your plugin is running out of memory. Check your boot disk and make sure it's not dangerously low on disk space. Try updating to the latest Indigo and plugin versions (1.4.2 at this writing). Restart things - first the plugin, then Indigo, then your Mac, in increasing order of inconvenience.

(The "memory" you're running out of is system-wide virtual memory; it's not just some plugin-specific resource. I'll take a look at the traceback to see if there's any sign of a memory-eating bug lurking.)

Perry, thanks.

Absolutely correct about the low VM/disk space. There was something that had witten 500Gb to /var/vm. And then the boot disk was full. A reboot cleared it and I have since updated to b10 and 1.4.2. There are loads of 'server' processes running on the machine, any one of which could be leaking memory, though it is usually a stable machine. I will monitor...

Many thanks,

Nic
