Sharepoint not downloading documents

Today I ran into a problem with Sharepoint 2007 not downloading documents from my document library. The files were pretty big (20 – 200 Megs). It was strange because suddenly the files which I was previously able to download also showed me an internal server error (500). Turned out, the issue was with not having enough disk space on sharepoint server :S Just cleared out some space on C drive of the sharepoint server and it started working fine.
