Exception - Method “banktransfer” is not available

[MagentoMagneto]

We get following exception error (on /var/log/exception.log) thrown by paypal module. We use paypal standard and hosted solutions.

I placed much efforts (tried our best) but could not find any solution. This error is being reported many times in a day since last few weeks. Our site is facing Service Unavailable and Segfault issues. So our managed server support asked to fix every exceptions and errors reported in magento logs.

Can anybody please help?

Any suggestion or potential clue is appreciated.

Thanks in advance

Did you update your theme recently? 

Does it have this behavior in the default version of Magento?

[MagentoMagneto]

Hey Brent,

No we have not updated theme since a year around. But we are going to soon. Also we have no default magento instance on our server for which we can check such issue and Our staging/development domain is synchronized with live domain recently so no idea. We are using magento version 1.8.0.0

I posted in other communities like stackexchange but no luck. I have been working in magento since three years but this is my first post to communities and issue for which I could not find solution yet.

Regards,

Bhavik

Did you customized paypal payment method, or customized how order is placed? it looks like paypal ipn is checking on an order which is placed with bank transfer method, and this method is not enable on your site. You maybe able to eliminate this exception by enabling back transfer method, but paypal ipn shouldn't check on other orders not placed by paypal at all. Double check the data send from ppaypal IPN, if that data(order id) is wrong, find out why.
