To: questions@freebsd.org Date: Tue, 23 Apr 1996 15:47:53 +0000 () X-Mailer: ELM [version 2.4 PL24] Content-Type: text Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Greetings, In the iijpp's modem.c, the routine Enqueue accepts unlimited mbufs to be queued. If there is too much traffic or the modem (or interface) has any hardware problems, this can cause the depletion of mbufs which eventually can cause the system to hang up. Have anyone ever looked into this ? This a a catch-22 situation - how many should we queue ? Best regards. Francis
