On Linux, if you delete ("unlink") a file while a process has it open, all that happens is that the directory entry is removed but the file itself remains until the process closes the file-descriptor. At this point, if there are no directory entries referencing the i-node of the file, the file itself is deleted.

Before the tcpdump processes were killed, you could have seen this using the lsof command.

I would guess that someone deleted the files but didn't kill the processes. The processes went on happy writing to the "deleted" files and filling up the filesystem until you came and killed them. Since killing the process implicitly closes all FDs, the files were finally deleted from the filesystem.

Does this help?
