Record gun sales on Black Friday this year caused the FBI’s background check system to crash twice, ABC News reports.

The FBI checked 154,873 backgrounds, a 20% spike over last year.

“The call centers experienced two short outages – one of 14 minutes and one of 18 minutes,” FBI spokesman Stephen Fischer told ABC News.

Background checks are required to determine whether the buyer has mental issues, felonies or other red flags for gun ownership.

The glitch, however, did not cause major delays, ABC New reported.
