I have a server running munin-node. Almost 200 times a day (probably about 2/3 of the instances of munin-node running) I get a message such as the following in the kern.log:

Oct 18 23:00:06 chez kernel: munin-update[22368] general protection rip:2aacef9b51bd rsp:7fffbbe6f5b0 error:0

I have been able to find essentially no information to explain why this is happening, or even what the error means. Is anyone familiar with anything like this? Any help would be hugely appreciated.
