This machine is our main www server, so I have to make it as stable as possible. I might be able to switch mpsafenet at night. By the way, I have accf_http(4) and accf_data(4) compiled in. But with or without them, I can easily get panic with mpsafenet in less half day. >=20 > I am going to keep it around for some time, so I can easisy do a full bt = or > variables. >=20 >=20 > Corresponding dmesg & sysctl output can be found at > https://kvip88.kvi.nl/~usov >=20 >=20 > -- > Best regards, > Alexander. >=20 > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" >
