Subject:   Help debugging non-sleepable lock panic on 6.2-RELEASE
Message-ID:  <45DDE5FD.4070404@mintel.com>

next in thread | raw e-mail | index | archive | help
This happens when we put our DELL PE2950 running MySQL 4.0.27 under load.

We have a kernel core dump, but I'm unsure what to do next.

It looks like the process triggering the problem is mysqld.

mysqld is compiled from ports with no switches,  and the threading
library is set to libthr using libmap.conf

We can usually reproduce this,  so if there's anything to try,  please
let me know.

Thanks in advance,

Jason.
