Hi all;

I have a Mysql 3.2.58 server running on Solaris 8 (the latest 3.2
version downloaded from Mysql.com).  The system is a Ultra-250 server
with multiple CPUs and 2G RAM.  There are many databases but they're not
large and the load on the system is not high at all.  We're using this
older version because we developed the database with the 3.2.x release,
years ago, and don't have the manpower to check to see if the newer
version will work or fix issues we might run into--although we may have
to find a way.


This version worked without problems for over a year.  But, for the last
4-6 weeks we've seen a problem once every 8-10 days where the server
hangs and will not come back.  Attempts to attach "normally" hang;
current operations hang; etc.  Using processlist shows some processes
which have existed for a long time; that may or may not be correct, I'm
not sure.  Almost all our queries are coming in through the Perl DBI/DBD
interface.

When I try to use mysqladmin kill they don't die; they do go to a state
of "killed" though.

When I try to myqladmin flush-tables, that hangs.  Flush-logs works but
there is nothing interesting in the logs.

When I try to run mysqld stop, the server process doesn't stop, although
most of the hung requests

When I run strace on the PID, I get this:

  lwp_sema_wait(0x1bfe50

then it hangs until I ^C.

I have to kill -9 the server PID to bring it down.  Then I check my
tables but so far (cross fingers) they've all been fine except they are
not shut properly, so I fix that with myisamchk.


Since I have not changed anything I suspect that the IS folks have
installed some new patch on the Solaris system which is causing this
problem to appear, but I have no proof of that.


Does anyone have any advice or information for me: places to look,
things to do, etc. etc.?  While so far we haven't lost any data this is
a problem since it seems like it will continue to happen.
