Sorry, I probably missed an important part: we're creating the FIFOs on nullfs mounts - the test script works great on plain UFS mounts, but the null layer seems to VREF the vnode once again, so v_usecount is 2, thus it is missong the check in fifo_cleanup(). regards, le -- Lukas Ertl eMail: [EMAIL PROTECTED] UNIX Systemadministrator Tel.: (+43 1) 4277-14073 Vienna University Computer Center Fax.: (+43 1) 4277-9140 University of Vienna http://mailbox.univie.ac.at/~le/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
