500 error while export data from reports.

I just create report name as contacts, I was trying exporting some data from there,

but when i exporting data, i get 500 error. Does anyone known this issue?

I pulled F&L name, company name, title, email, address, phone . it was only 5000 records.

Did the 500 error occur immediately or did the export time out?

Are there any errors in your suitecrm.log or in your server logs?
