ListData.svc An error occurred while processing this request. HTTP 500

Hi dear community I'm having a problem with retrieving information from http://MySPSite/_vti_bin/ListData.svc/PartNumberPI()?$filter=Title eq '0110E03150' where PartNumberPI is a list (with 38k items) when i type that URL on my browser i got the error

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<error><code/><message xml:lang="en-US">An error occurred while processing this request.</message></error>

so i did some tests if i type the following URL it works

http://MySPSite/_vti_bin/ListData.svc/PartNumberPI()

the problem is when i added OData operators like starswith or eq for example.

More details: if i use OData operators in other list it works perfects the problem is only with this list when i add filters like i said if i retrieve information from PartNumberPI without any filter i got all the information, the problem just occur when i add filters in this list, the other ones works fine with or without filters.

any help is appreciated

thanks in advance

i almost forgot to say I'm working with SharePoint 2010 and this is the columns and type of my list PartNumberPI
