Failed to fork child: Resource temporarily unavail *solved*

[plex]

Today I rebooted my MBP red, to get the latest firmware.

A few hours later, I got mail from wunderground that my station stopped reporting. I tried to access the user interface, but got the message "Failed to fork child: Resource temporarily unavailable"

What does it mean?

It's running after a power cycle with a few errors - I don't know if it's something to worry about (database is locked).

If it ain't broke don't fix it

After one hour it crashed again

I get the same error trying to access user interface, and ip-adress from lcd is gone. However it's still visible is my lan...

Also display is still showing new weather data, so it's not like completely crashed.

How can I revert?

I think my old version was dated 10th of feb.

Yet another 55 minutes and this happened

Should be solved with latest update. Please reboot.
