problem possibly related to multi-ip jail patch?

Hi all,

I've been experiencing problems with one of the machines running  
FreeBSD 7.1-PRERELEASE #2: Thu Oct 16 20:23:09 CEST 2008 with the  
multi-ip patch bz_jail7-20080920-01-at150161.diff, and I'm wondering  
if it possibly related to the patch - in any case, any advice would be  
very welcome.

It happens that mysql (tried both 4.0 and 5.1, in 2 separate jails),  
at some time stop responding to connections, and mysql gets stuck in  
sbwait state. It is only killable with kill -9 <pid>

each of the two mysqlds is running in a jail on one private IP,  
serving connections to a webserver nearby - the latter having one  
public and one private IP, communicating with the other jail via the  
private network.

I also experienced two complete system hangs (which must not be  
necessarily related to the mysql problem) both during a shutdown -r  
now. one was a panic, in another case the machine was still pingable  
but did not shut down completely. I could only reset it over the DRAC.  
here's a screenshot I made over the Dell RAC:

Since I'm also using zfs there and the kernel has been built with the  
DTRACE options.

any advice (also about which more details that I should/could provide)  
would be very welcome...

thanx && regards,
