Death or Sleep
Vincent's Word Studies
Be dead ( κοιμηθῇ )
Lit., have fallen asleep. See on Acts 7:60; see on 2 Peter 3:4; compare Romans 7:2, where the usual word for die, ἀποθάνῃ is used. In that passage Paul is discussing the abstract question. Here the inference is more personal, which is perhaps the reason for his using the more tender expression.

Jamieson-Fausset-Brown Bible Commentary
1Co 11:30. weak … sickly - He is "weak" who has naturally no strength: "sickly," who has lost his strength by disease [Tittmann, Greek Synonyms of the New Testament].
sleep—are being lulled in death: not a violent death; but one the result of sickness, sent as the Lord's chastening for the individual's salvation, the mind being brought to a right state on the sick bed (1Co 11:31).
People's New Testament
1Co 11:30 For this cause, many are weak and sickly among you, and many sleep. Some have held that this means that the improper observance of the supper has made many weak and sickly Christians, and some had even died spiritually. Others hold that physical judgments had been sent, and some sickened and others died. The last view is most generally held.
